Overview of JDK 7 Support in NetBeans IDE

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

The NetBeans IDE supports Java 7 language features, such as the diamond operator, strings in switch, multicatch, etc. When you use these constructs in your code, the IDE recognizes them, offers correct classes in code completion, correctly highlights errors, and lets you automatically fix syntax. Thus, the NetBeans IDE helps you write code that is compatible with the Java Language Specification, Java SE 7 Edition.

In this tutorial, you learn how the IDE handles Java 7 language constructs.

To complete this tutorial, you need the software and resources listed in the following table.

Software or Resource Version Required

version 7.4 or 8.0

version 7 or 8

Lỗi thường gặp:

Trường hợp khi cài xong mà Netbeans không chạy thì lý do là các bạn chưa cấu hình JDK các bạn có thể khắc phục như sau:

Bước 1 : Bạn Click chuột phải lên Computer(Win 7), This PC(Win 8, 10) chọn Properties.

Bước 2 : Bạn chọn Advanced system settings.

Bước 3 : Bạn chọn mục Advanced sau đó chọn Environment Variables.

How to install NetBeans IDE 20 on Windows 11 (64 bit) [ 2024 Update ] JDK 21 | Complete guide

Using New JDK 7 Language Constructs: Switch Statement

JDK 7 brings a number of new features and enhancements in different areas, including internationalization, I/O and networking, security, etc. The best way to illustrate the JDK 7 support by the IDE’s Java Editor is to demonstrate a few language changes introduced by Project Coin.

One of these changes is a “String in a switch”. In the previous versions of Java, the argument of

switch

had to be only of the following primitive data types:

byte

,

short

,

char

,

int

, or

enum

. Starting from JDK 7, you can use arguments of type

String

in the expression of a

switch

statement.

  1. Open


    SwitchTest.java

    and add the following code. This small sample displays RGB codes for several colors. With JDK 7, the

    color

    variable can be a

    String

    .


package switchtest; public class SwitchTest { public static void main(String[] args) { String color = "red"; String colorRGB; switch (color.toLowerCase()) { case "black": colorRGB = "000000"; break; case "red": colorRGB = "ff0000"; break; case "green": colorRGB = "008000"; break; case "blue": colorRGB = "0000ff"; break; default: colorRGB = "Invalid color"; break; } System.out.println(colorRGB); } }

If the pasted code is formatted incorrectly in the editor, press Alt-Shift-F to reformat.

  1. In the Projects window, right-click the project’s node and choose Run File. You will see the output of the application, which is the RGB code for the red color. You can see that the build is successful and the application works when the target platform and source format is JDK 7.

  1. Let’s rollback to using JDK 6 and test how the application is complied with the JDK 6 compiler. In the Projects window, right-click the project’s node and choose Properties. In the Sources category, set the Source/Binary Format to


    JDK 6

    and click OK. You can immediately see that the JDK6 parser does not recognize the syntax. The compilation fails because of the incompatible variable type.

  1. Now, let’s rewrite the code using the


    if-then-else

    statement instead of

    switch

    as follows:


package switchtest; public class SwitchTest { public static void main(String[] args) { String color = "red"; String colorRGB; if (color.equals("black")) { colorRGB = "000000"; } else if (color.equals("red")) { colorRGB = "ff0000"; } else if (color.equals("green")) { colorRGB = "008000"; } else if (color.equals("blue")) { colorRGB = "0000ff"; } else { colorRGB = "Invalid color"; } System.out.println(colorRGB); } }

With JDK 7 being the Source/Binary Format, the IDE recognizes such cases and offers you to convert them to

switch

as shown in the picture below.

Click the hint and the

if-then-else

construct will be automatically converted to exactly the same

switch

that we had before.

Checking the Project Configuration

To check your project is configured to use the registered JDK for compilation, running, and debugging:

  1. Create a Java project by choosing File > New Project and selecting Java Application as the project type.

  2. Click Next.

  3. Type


    SwitchTest

    as the project name and specify its location.

  4. Click Finish.

  5. In the Projects window, right-click the


    SwitchTest

    project’s node and choose Properties > Libraries. On this tab, ensure JDK 1.7 is selected in the list of Java Platforms.

  1. Switch to the Sources tab of the Project Properties window and ensure JDK 7 is chosen as the Source/Binary Format.

  1. Click OK to close the Project Properties dialog box. Your project is configured to recognize Java 7 language features.

JDK 7 Support: More Examples

To demonstrate how the IDE’s Java Editor recognizes and automatically fixes code to be compliant with the JDK 7 language spec, let’s use a dummy code snippet, which is meaningless but contains all the major language improvements.

When walking through this dummy code snippet and applying editor hints, you will see the following examples of how to:

  • Take advantage of automatic type inference, when the Java compiler is able to infer the type of a generic instance without the need to explicitly specify it. The so-called diamond operator is used to flag the type inference case.

  • Use improved exception handling or multi-catch, when one


    catch

    block can be used for several types of exceptions.

  • Use the new syntax of resource closure statements introduced by the Automatic Resource Management feature.

    1. Replace the previous application code in the same


      SwitchTest.java

      file with the following code:


package switchtest; import java.io.FileInputStream; import java.lang.reflect.Method; import java.io.IOException; import java.lang.reflect.InvocationTargetException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; public class SwitchTest { public void test() throws IOException { List

list = new ArrayList

(); HashMap

map = new HashMap

(); HashMap

map2 = new HashMap

(); String a = "ehlo"; try { Method m = Object.class.getMethod("toString"); m.invoke(this); } catch(NoSuchMethodException e) { e.printStackTrace(); } catch(InvocationTargetException e) { e.printStackTrace(); } catch(IllegalAccessException e) { e.printStackTrace(); } FileInputStream in = null; try { in = new FileInputStream("foo.txt"); int k; while ((k = in.read()) != -1) { System.out.write(k); } } finally { if (in != null) { in.close(); } } } }






  1. Note that the IDE displays several hints, as shown above in this tutorial, of how you can optimize your code for the JDK 7 spec. Simply click on each hint and select the suggested action.

  2. Finally, after you accept all the suggestions, you should have the JDK 7 compatible code shown below.

Building from Source

To build Apache NetBeans 16 from source you need:

  1. A distribution of OpenJDK 11.

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

Once you have everything installed then:

  1. Unzip netbeans-16-source.zip in a directory of your liking.


  1. cd

    to that directory, and then run

    ant

    to build the Apache NetBeans IDE. Once built you can run the IDE by typing

    ./nbbuild/netbeans/bin/netbeans
