JAVA - How To Design Login And Register Form In Java Netbeans

Building, Running, and Distributing the Application

Once you are satisfied that your application works properly, you can prepare the application for deployment outside of the IDE. In this section you will build the application’s JAR file and then run the JAR file from the command line.

Building the Application

The main build command in the IDE is the Clean and Build command. The Clean and Build command deletes previously compiled classes and other build artifacts and then rebuilds the entire project from scratch.

There is also a Build command, which does not delete old build artifacts, but this command is disabled by default. See About Building Java Projects in Developing Applications with NetBeans IDE for more information.

To build the application, press Shift+F11 or, if

Main.java

is open in the editor, select Run > Clean and Build Project (MyApp) from the menu bar or, in the projects window right-click on the MyApp node and select Clean and Build.

Output from the Ant build script appears in the Output window, If the window does not appear automatically, open it manually by choosing Window > Output from the menu bar.

When you clean and build your project, the following things occur:

  • Output folders that have been generated by previous build actions are deleted, ” cleaned “. In most cases, these are the


    build

    and

    dist

    folders.


  • build

    and

    dist

    folders are added to your project folder, hereafter referred to as the PROJECT_HOME folder. You can view these folders in the Files window.
  • All of the sources are compiled into


    .class

    files, which are placed into the

    PROJECT_HOME/build

    folder.

  • A JAR file containing your project is created inside the


    PROJECT_HOME/dist

    folder.

  • If you have specified any libraries for the project, in addition to the JDK, a


    lib

    folder is created in the

    dist

    folder. The libraries are copied into

    dist/lib

    .

  • The manifest file in the JAR is updated to include entries that designate the main class and any libraries that are on the project’s classpath.

You can view the contents of the manifest in the IDE’s Files window. After you have built your project, switch to the Files window and navigate to

To find more about manifest files, you can read this chapter from the Java Tutorial.

Running the Application Outside of the IDE

To run the application outside of the IDE:

On your system, open up a command prompt or terminal window.

In the command prompt, change directories to the

MyApp/dist

directory.

At the command line, type the following statement:


java -jar MyApp.jar However we all feel zealous

The application then executes and returns the following output as shown in the image below:


Result = Hello

Distributing the Application to Other Users

Now that you have verified that the application works outside of the IDE, you are ready to distribute the application.

To distribute the application:

On your system, create a zip file that contains the application JAR file (

MyApp.jar

) and the accompanying

lib

folder that contains

MyLib.jar

.

Send the file to the people who will use the application. Instruct them to unpack the zip file, making sure that the

MyApp.jar

file and the

lib

folder are in the same folder.

Instruct the users to follow the steps in the Running the Application Outside of the IDE section above.

Building from source

You can of course build Apache NetBeans from source. To do so:

  1. Clone the https://github.com/apache/netbeans GitHub repository.

  2. Install an LTS release of the Java Development Kit. (JDK 11+)

  3. Install Apache Ant 1.10 or greater (https://ant.apache.org/).

  4. Set or verify that the environment variables JAVA_HOME and ANT_HOME are properly defined.

Once you’re all set, enter the

netbeans

directory:

  • To build the Apache NetBeans IDE, according to the JDK type


    ant build

    in the command line or shell of your choice

  • The build will generate a binary zip bundle of the IDE at


    ./nbbuild/NetBeans-

    -release.zip


    , and you can:

    • Extract that zip in a place of your choosing and run


      netbeans/bin/netbeans

      (or

      netbeans/bin/netbeans.exe

      on Windows).

    • Type


      ant tryme

      to run the Apache NetBeans IDE directly from the build folder rather than the zip for development purposes.

For details, go here: https://cwiki.apache.org/confluence/display/NETBEANS/Development+Environment

Now that you have built Apache NetBeans from source you may want to submit a pull request.

How do I obtain a source file for a Java class and open it in the editor?

Note: These pages are being reviewed.

Sometimes it is necessary to open source code for a Java file from your NetBeans plug-in. The source code may be located in the currently open projects, in a library or in the platform JRE. It is assumed that libraries and platform JRE have associated sources in your environment. The associations are configured from the Tools > Libraries and Tools > Java Platform menu items.

Here is an example of how to find a

FileObject

corresponding to the class

javax.swing.JComponent

:


String classResource = "javax/swing/JComponent.java"; for (FileObject curRoot : GlobalPathRegistry.getDefault().getSourceRoots()) { FileObject fileObject = curRoot.getFileObject(classResource); if (fileObject != null) { // source file object found // do something, e.g. openEditor(fileObject, lineNumber); return; } }

In the

if

block you can do something with the source file you found.
For example, you can open it in the Java editor.

Static Code Analysis in the NetBeans IDE Java Editor

This tutorial needs a review. You can edit it in GitHub following these contribution guidelines.

The NetBeans IDE Java Editor has a static code analysis feature, which is a tool for finding potential problems and detecting inconsistencies in your source code.

In this tutorial, you will learn how to perform static analysis of your Java code using NetBeans Java Hints without actually running your applications.

JAVA - How To Design Login And Register Form In Java Netbeans
JAVA – How To Design Login And Register Form In Java Netbeans

Summary

This tutorial covers most frequent usages of the static code analysis feature in the NetBeans IDE. Please note that with the static code analysis functionality you can also perform custom refactorings at a project scope, or apply particular refactoring configurations to several projects open in the IDE, etc.

The Java Tutorials have been written for JDK 8. Examples and practices described in this page don’t take advantage of improvements introduced in later releases and might use technology no longer available.See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases.See JDK Release Notes for information about new features, enhancements, and removed or deprecated options for all JDK releases.

It’s time to write your first application! These detailed instructions are for users of the NetBeans IDE. The NetBeans IDE runs on the Java platform, which means that you can use it with any operating system for which there is a JDK available. These operating systems include Microsoft Windows, Solaris OS, Linux, and Mac OS X.

To write your first program, you’ll need:

The Java SE Development Kit (JDK 7 has been selected in this example)

The NetBeans IDE

Your first application,

HelloWorldApp

, will simply display the greeting “Hello World!” To create this program, you will:

Create an IDE project

When you create an IDE project, you create an environment in which to build and run your applications. Using IDE projects eliminates configuration issues normally associated with developing on the command line. You can build or run your application by choosing a single menu item within the IDE.

Add code to the generated source file

A source file contains code, written in the Java programming language, that you and other programmers can understand. As part of creating an IDE project, a skeleton source file will be automatically generated. You will then modify the source file to add the “Hello World!” message.

Compile the source file into a .class file

The IDE invokes the Java programming language compiler

(javac)

, which takes your source file and translates its text into instructions that the Java virtual machine can understand. The instructions contained within this file are known as bytecodes.

Run the program

The IDE invokes the Java application launcher tool (

java

), which uses the Java virtual machine to run your application.

To create an IDE project:

Launch the NetBeans IDE.

On Microsoft Windows systems, you can use the NetBeans IDE item in the Start menu.

On Solaris OS and Linux systems, you execute the IDE launcher script by navigating to the IDE’s

bin

directory and typing

./netbeans.

On Mac OS X systems, click the NetBeans IDE application icon.

In the NetBeans IDE, choose File | New Project….

NetBeans IDE with the File | New Project menu item selected.

In the New Project wizard, expand the Java category and select Java Application as shown in the following figure:

NetBeans IDE, New Project wizard, Choose Project page.

In the Name and Location page of the wizard, do the following (as shown in the figure below):

In the Project Name field, type

Hello World App

.

In the Create Main Class field, type

helloworldapp.HelloWorldApp

.

NetBeans IDE, New Project wizard, Name and Location page.

Click Finish.

The project is created and opened in the IDE. You should see the following components:

The Projects window, which contains a tree view of the components of the project, including source files, libraries that your code depends on, and so on.

The Source Editor window with a file called

HelloWorldApp.java

open.

The Navigator window, which you can use to quickly navigate between elements within the selected class.

NetBeans IDE with the HelloWorldApp project open.

It may be necessary to add JDK 8 to the IDE’s list of available platforms. To do this, choose Tools | Java Platforms as shown in the following figure:

Selecting the Java Platform Manager from the Tools Menu

If you don’t see JDK 8 (which might appear as 1.8 or 1.8.0) in the list of installed platforms, click Add Platform, navigate to your JDK 8 install directory, and click Finish. You should now see this newly added platform:

The Java Platform Manager

To set this JDK as the default for all projects, you can run the IDE with the

--jdkhome

switch on the command line, or by entering the path to the JDK in the

netbeans_j2sdkhome

property of your

INSTALLATION_DIRECTORY/etc/netbeans.conf

file.

To specify this JDK for the current project only, select Hello World App in the Projects pane, choose File | Project Properties (Hello World App), click Libraries, then select JDK 1.8 in the Java Platform pulldown menu. You should see a screen similar to the following:

The IDE is now configured for JDK 8.

When you created this project, you left the Create Main Class checkcbox selected in the New Project wizard. The IDE has therefore created a skeleton class for you. You can add the “Hello World!” message to the skeleton code by replacing the line:

// TODO code application logic here

with the line:

System.out.println(“Hello World!”); // Display the string.

Optionally, you can replace these four lines of generated code:

/** * * @author */

with these lines:

/** * The HelloWorldApp class implements an application that * simply prints “Hello World!” to standard output. */

These four lines are a code comment and do not affect how the program runs. Later sections of this tutorial explain the use and format of code comments.

Be Careful When You Type


javac) and launcher (


java) are case-sensitive, so you must capitalize consistently.


HelloWorldAppis not the same as


helloworldapp.

Save your changes by choosing File | Save.

The file should look something like the following:

/* * To change this template, choose Tools | Templates * and open the template in the editor. */ package helloworldapp; /** * The HelloWorldApp class implements an application that * simply prints “Hello World!” to standard output. */ public class HelloWorldApp { /** * @param args the command line arguments */ public static void main(String[] args) { System.out.println(“Hello World!”); // Display the string. } }

To compile your source file, choose Run | Build Project (Hello World App) from the IDE’s main menu.

The Output window opens and displays output similar to what you see in the following figure:

Output window showing results of building the HelloWorld project.

If the build output concludes with the statement

BUILD SUCCESSFUL

, congratulations! You have successfully compiled your program!

If the build output concludes with the statement

BUILD FAILED

, you probably have a syntax error in your code. Errors are reported in the Output window as hyperlinked text. You double-click such a hyperlink to navigate to the source of an error. You can then fix the error and once again choose Run | Build Project.

When you build the project, the bytecode file

HelloWorldApp.class

is generated. You can see where the new file is generated by opening the Files window and expanding the Hello World App/build/classes/helloworldapp node as shown in the following figure.

Files window, showing the generated .class file.

Now that you have built the project, you can run your program.

From the IDE’s menu bar, choose Run | Run Main Project.

The next figure shows what you should now see.

The program prints “Hello World!” to the Output window (along with other output from the build script).

Congratulations! Your program works!

The next few pages of the tutorial will explain the code in this simple application. After that, the lessons go deeper into core language features and provide many more examples. Although the rest of the tutorial does not give specific instructions about using the NetBeans IDE, you can easily use the IDE to write and run the sample code. The following are some tips on using the IDE and explanations of some IDE behavior that you are likely to see:

Once you have created a project in the IDE, you can add files to the project using the New File wizard. Choose File | New File, and then select a template in the wizard, such as the Empty Java File template.

You can compile and run an individual file (as opposed to a whole project) using the IDE’s Compile File (F9) and Run File (Shift-F6) commands. If you use the Run Main Project command, the IDE will run the file that the IDE associates as the main class of the main project. Therefore, if you create an additional class in your HelloWorldApp project and then try to run that file with the Run Main Project command, the IDE will run the

HelloWorldApp

file instead.

You might want to create separate IDE projects for sample applications that include more than one source file.

As you are typing in the IDE, a code completion box might periodically appear. You can either ignore the code completion box and keep typing, or you can select one of the suggested expressions. If you would prefer not to have the code completion box automatically appear, you can turn off the feature. Choose Tools | Options | Editor, click the Code Completion tab and clear the Auto Popup Completion Window check box.

If you want to rename the node for a source file in the Projects window, choose Refactor from IDE’s main menu. The IDE prompts you with the Rename dialog box to lead you through the options of renaming the class and the updating of code that refers to that class. Make the changes and click Refactor to apply the changes. This sequence of clicks might seem unnecessary if you have just a single class in your project, but it is very useful when your changes affect other parts of your code in larger projects.

For a more thorough guide to the features of the NetBeans IDE, see the NetBeans Documentation page.

  • Creating and Editing Java Source Code
  • Compiling and Running the Application
  • Testing and Debugging the Application
  • Building, Running, and Distributing the Application
  • Other Common Tasks

The following short tutorial takes you through some of the basic steps of developing a Java SE application in the NetBeans IDE. This tutorial assumes you already have some familiarity with developing Java applications. Along the way, you will see some of the IDE’s features that simplify application development.

You will create an application that converts several words into a single word that contains one letter from each of the other words. The resulting word is called an acrostic.

This tutorial takes approximately 30 minutes to complete. If you would like to do a quicker Hello World tutorial, see the NetBeans IDE Java Quick Start Tutorial.

Testing and Debugging the Application

Now you will create and run a test for the project using JUnit and then run the application in the IDE’s debugger to check for errors. In the JUnit test, you will test the LibClass by passing a phrase to the

acrostic

method and using an assertion to indicate what you think the result should be.

Creating JUnit Tests

To create a JUnit test, from the Projects window select the

LibClass.java

node and press:

Windows™/Linux

Ctrl+Shift+U

macOS™

Command+Shift+U

or, select Tools > Create/Update Tests from the menu bar or, in the Projects window, right-click the

LibClass.java

node and and select Tools > Create/Update Tests.

In the Create/Update Tests dialog box, click OK to run the command with the default options.

In the Projects window you will see that the IDE has created the

org.me.mylib

package, the

LibClassTest.java

file in the MyLib > Test Packages folder and, created the MyLib > Test Libraries folder. Finally the file

LibClassTest.java

is opened in the editor.

In the Projects window, right-click the Test Libraries node and select Properties. In the Project Properties – MyLib window, select Categories: Libraries. In the right-hand pane select the Compile Tests tab and click the ` + ` button to the right of the Classpath heading. From the pop-up list select Add Library, from the Global Libraries folder select

JUnit 4.x

and click Add Library repeat, this time selecting the

Hamcrest 1.x

library. Select the Run Tests tab and add these libraries to its classpath.

In

LibClassTest.java

, delete the body of the

public void testAcrostic()

method and, in place of the deleted lines, type or paste in the following:


System.err.println("Running testAcrostic..."); String result = LibClass.acrostic(new String[]{"fnord", "polly", "tropism"}); assertEquals("Correct value", "foo", result);

Then Save the file.

Running JUnit Tests

In the Projects window, select the MyLib project node and press:

Windows™/Linux

Alt+F6

macOS™

Ctrl+F6

or, select Run > Test Project (MyLib) from the menu bar or, right-click the MyLib project node and select Test. A notification pops up telling you “Tests completed successfully for project: MyLib”, and then instructs you to open the Test Results window, were you will receive confirmation of success.

You can also run a single test file rather than testing the entire project. Right-click the

LibClass.java

node in the Projects window and choose Run > Test File. Alternatively, if

LibClassTest.java

is open in the editor, select Run > Test File from the menu bar.

The JUnit API documentation is available from the IDE. To look for Javadoc references, select Help > Javadoc References from the menu bar and select

JUnit

.

If this is the first time you try to access Javadoc in the IDE, you need to first choose Help > Javadoc References > More Javadoc.

You can learn more about JUnit by visiting http://www.junit.org

Debugging the Application

In this section, you will use the debugger to step through the application and watch the values of variables change as the acrostic is assembled.

To run the application in the debugger:

In the

LibClass.java

file, go to the

acrostic

method and place the insertion point anywhere inside

b.append(args[i].charAt(i));

, then set a breakpoint by pressing:

Windows™/Linux

Ctrl+F8

macOS™

Command+F8

or, select Debug > Toggle Line Breakpoint from the menu bar or, in the left hand margin right-click the specified line and select Breakpoint > Toggle Line Breakpoint.

Select the MyApp project node in the Projects window and, press:

Windows™/Linux

Ctrl+F5

macOS™

Shift+F5

or, select Debug > Debug Project (MyApp) from the menu bar or, right-click and select Debug. The IDE opens the Debugging window and runs the project in the debugger until the breakpoint is reached.

Select the Variables window in the bottom of the IDE and expand the

args

node. The array of strings contains the phrase you entered as the command arguments.

Press F7 or, select Debug > Step Into from the menu bar to step through the program and watch the variable change as the acrostic is constructed.

When the program reaches the end, the debugger windows close.

Windows™/Linux

Ctrl+N

macOS™

Command+N

or, select File > New File… from the menu bar. Then in the New File window select: Project: MyLib, Categories: Java and File Types: Java Class then click Next.

In the New Java Class window, type: Class Name: LibClass and Package: org.me.mylib. Click Finish and LibClass.java opens in the source editor.

In

LibClass.java

, place the cursor on the line after the class declaration

public class LibClass {

.

Type or paste in the following method code:


public static String acrostic(String[] args) { StringBuilder b = new StringBuilder(); for (int i = 0; i < args.length; i++) { if (args[i].length() > i) { b.append(args[i].charAt(i)); } else { b.append('?'); } } return b.toString(); }

If the code that you pasted in is not formatted correctly, press:

Windows™/Linux

Alt+Shift+F

macOS™

Ctrl+Shift+F

or, Source > Format from the menu bar or, right-click Format to reformat the entire file. Then save your file:

Windows™/Linux

Ctrl+S

macOS™

Command+S

or, select File > Save from the menu bar.

Editing a Java File

Now you will add some code to class

Main.java

. In doing so, you will see the source editor’s code completion and, code template features.

Select the

Main.java

tab in the source editor. If it isn’t already open, select the Projects window and expand MyApp > Source Packages > acrostic and either: double-click

Main.java

or, right-click and select Open.

In the method

main

, delete the comment:

// TODO code application logic here

and, in its place type the following:


String result = Li

At this point stop typing but leave the cursor immediately after

Li

. Invoke code completion by pressing Ctrl+Space, a short list of options appears. However, the class that you want,

LibClass

might not be there. If you press Ctrl+Space again a longer code completion list appears containing

LibClass

, select

LibClass

and press Enter. The IDE fills in the rest of the class name and also automatically creates an import statement for the class.

The IDE also opens a box above the code completion box that displays Javadoc information for the selected class or package. Since there is no Javadoc information for this package, the box displays a “Cannot find Javadoc” message.

In the main method, type a period ( ) after

LibClass

, the code completion box opens again. Select the

acrostic(String[]args)

method and press Enter. The IDE fills in the

acrostic

method and highlights the

args

parameter, press Enter again to accept

args

as the parameter, end the line with a semicolon ( ). The line should look, as follows:


String result = LibClass.acrostic(args);

Press Enter to start a new line. Then type

sout

and press Tab. The

sout

abbreviation expands to

System.out.println("");

with the cursor positioned between the quotation marks. Type

Result =

inside the quotation marks and

+ result

after the end quotation mark. The final line should look like the following line.


System.out.println("Result = " + result);

Save the file.

The description of the currently selected in the tree view finding is displayed on the right.

If you want to leave some part of your code that is reported as problematic as is, the IDE allows you to suppress the warning for this code to leave it without any changes. You can double-click a warning in the tree view of the Inspector Window to go to the Source Editor.

Press Alt+Enter, click the black arrow pointing to the right at the end of the displayed hint, and choose

Verifying Java Code against NetBeans Java Hints

The

NetBeans Java Hints

configuration available in the IDE enables you to verify if the predefined coding standard rules are satisfied by the source code under consideration. In other words, it applies a set of NetBeans Java Hints (also known as code inspections) to your Java source files.

Other Common Tasks

You have now completed the main part of the tutorial, but there are still some basic tasks that have not been covered. This section includes a few of those tasks.

Making the Javadoc Available in the IDE

To view the Java SE API documentation in the NetBeans IDE, select either: Source > Show Documentation or, Window > IDE Tools > Javadoc Documentation from the menu bar.

However, for some third-party libraries, API documentation is not available. In these cases, the Javadoc resources must be manually associated with the IDE.

If you have not already installed the Javadoc for your JDK then go to:

and, download the file.

To install, select Tools > Java Platforms from the menu bar and, in the Java Platform Manager window select the Javadoc tab and click Add ZIP/Folder…. Navigate to the download file, select and then click the Add ZIP/Folder button, finally click Close.

Generating Javadoc for a Project

You can generate compiled Javadoc documentation for your project based on Javadoc comments that you have added to your classes.

To generate Javadoc documentation for a project:

From the Projects window select the MyLib project node then select Run > Generate Javadoc (MyLib) from the menu bar.

The generated Javadoc is added to the

dist

folder of the project. In addition, the IDE opens a web browser that displays the Javadoc.

Project Setup

The application you create will contain two projects that will use Ant to handle the build process:

  • A Java Class Library project, MyLib, in which you will create a utility class.

  • A Java Application project, MyApp, with a main class that implements a method from the library project’s utility class.

After you create the projects, you will add the library project, MyLib, to the classpath of the application project, MyApp. Then you will code the application. The library project will contain a utility class with a method named

acrostic

. The method

acrostic

takes an array of words as a parameter and then generates an acrostic based on those words. The MyApp project will contain a class Main that calls method

acrostic

and passes the words that are entered as arguments when the application is run.

Strictly speaking, two projects are not needed for such a simple application. This tutorial uses two projects to demonstrate features that you might need for a more complex application.

Creating a Java Class Library Project

To open a new Java project, press:

Windows™/Linux

Ctrl+Shift+N

macOS™

Command+Shift+N

or, select File > New Project… from the menu bar. Then Choose Project by selecting Categories: Java with Ant and Projects: Java Class Library, then click Next >.

For Name and Location, set Project Name: MyLib. Change Project Location: to any directory on your computer. From now on, this tutorial refers to this directory as

NetBeansProjects

.

The specified path is then shown as Project Folder:

NetBeansProjects/MyLib

Optionally, select Use Dedicated Folder for Storing Libraries checkbox and specify the location for the libraries Folder:. See Sharing a Library with Other Users in Developing Applications with NetBeans IDE for more information on this option.

Finally, click Finish. The MyLib project will be created and opens in the Projects window.

Creating a Java Application Project

Open a new Java Project, as shown above. Then Choose Project by selecting Categories: Java with Ant and Projects: Java Application, then click Next >.

for Name and Location, set Project Name: MyApp. Make sure the Project Location is set to

NetBeansProjects

.

Optionally, select the Use Dedicated Folder for Storing Libraries checkbox.

Ensure that the Create Main Class checkbox is selected and, enter acrostic.Main as the main class.

Finally, click Finish. The MyApp project is displayed in the Projects window and Main.java opens in the source editor.

Configuring the Compilation Classpath

Since class MyApp is going to depend on class MyLib, you have to add MyLib to the classpath of MyApp. Doing so also ensures that classes in the MyApp Project can refer to classes in the MyLib Project without causing compilation errors. In addition, this enables you to use code completion in the MyApp Project to fill in code based on the MyLib Project. In the IDE, the classpath is visually represented by the Libraries node.

To add the library’s utility classes to the project classpath:

In the Projects window, right-click the Libraries node for the MyApp project and choose Add Project… as shown in the image below.

If necessary, in the Add Project window browse to

NetBeansProjects

and, select the MyLib project folder. When you do so, you will see Project Name: MyLib and, Project JAR Files: dist/MyLib.jar can be added to the project.

Notice that a JAR file is shown for MyLib even though you have not actually built one yet. This JAR file will get built when you build and run the MyApp project.

Select Add Project JAR Files then expand the Libraries node of MyApp in the Projects window and, you will see that MyLib project’s JAR file has been added to the MyApp project’s classpath.

Compiling and Running the Application

Now you need to set the main class and execution arguments so that you can run the project.

By default, the projects have been created with the Compile on Save feature enabled, so you do not need to compile your code first in order to run the application in the IDE. For more information, see Compiling a Single Java File in Developing Applications with NetBeans IDE.

Setting the Main Class and Execution Arguments

The output of this program is based on arguments that you provide when you run the program. As arguments, you will provide five words, from which the acrostic “Hello” will be generated. The acrostic is assembled from the first letter of the first word, the second letter of the second word, the third letter of the third word, and so on.

To add the arguments for the IDE to use when running the application:

From the Projects window, right-click the MyApp project node and select Properties. The Project Properties window opens, select the Categories: Run node in the dialog’s left-hand pane. In the right-hand pane set Arguments: However we all feel zealous and select OK.

Running the Application

Now that you have created the application and provided runtime arguments for the application, you can test run the application in the IDE.

To run the application in the IDE:

First, press

F11

to clean and build your project or, in the Projects window right-click the MyApp project node and choose Clean and Build or, select Run > Clean and Build Project (MyApp) from the menu bar.

Then, you can press

F6

or, in the Projects window right-click the MyApp project node and choose Run or, select Run > Run Project (MyApp) from the menu bar .

In the Output window, you should see the output from the program,

Result = Hello

, the acrostic of the phrase that was passed as an argument to the program.
