Configuration tips for using NetBeans for cross-platform Java development on Linux systems

Overview:
NetBeans is a powerful and easy-to-use cross-platform development environment, especially suitable for Java development. This article will introduce the configuration techniques for using NetBeans for cross-platform Java development on Linux systems to help readers develop Java projects more efficiently.

Preparation:
Before you begin, you need to ensure that NetBeans has been installed correctly on the Linux system. You can download the latest version from the NetBeans official website and follow the prompts to install it.

Configure JDK path:
Before using NetBeans for Java development, you need to configure the JDK path. First, open NetBeans and click "Tools" in the menu bar, then select "Options".

Next, in the "Options" interface, select the "Java" tab, and then click the "Add" button. In the pop-up dialog box, enter the JDK installation path, such as "/usr/lib/jvm/java-8-openjdk-amd64". Click "OK" to save the configuration.

Create a Java project:
After the configuration is completed, you can start creating a Java project. Click the "File" menu on the NetBeans main interface and select "New Project".

In the pop-up dialog box, select "Java", and then select "Java Application" as the project type. Click the "Next" button.

Next, enter the name and location of the project. Fill in the project name and storage location in the "Project Name" and "Project Location" fields respectively. Click the "Finish" button.

Writing Java code:
After creating the project, you can start writing Java code. In the "Projects" window to the left of the project, expand the project name, then double-click the "src" folder, and then double-click the "package" folder.

Right-click the package folder, select "New", and then select "Java Class". In the pop-up dialog box, fill in the name of the class, such as "HelloWorld", and then click the "Finish" button.

Write Java code in the editor, for example:

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

Run the Java program:
After writing the Java code, you can run the program directly in NetBeans. Click the green run button in the upper left corner of the editor, or use the shortcut "Shift F6" to run the program.

If everything goes well, the console window will display "Hello, World!".

Debugging Java programs:
In addition to running programs, NetBeans also provides powerful debugging functions. You can set breakpoints in the code to pause the execution of the program during running and view information such as variable values ​​and call stacks.

To set a breakpoint, simply click on the line number area on the left side of the code editor. After setting a breakpoint, when you run the program and trigger the breakpoint, the program will stop at the breakpoint and display debugging information.

Import an existing project:
If you already have an existing Java project and want to develop and debug it in NetBeans, you can use NetBeans' import function.

Click the "File" menu on the NetBeans main interface and select "New Project". In the dialog box that pops up, select "Java" and then select "Java Project with Existing Sources" as the project type. Click the "Next" button and follow the prompts to select the project folder and settings.

Summary:
This article introduces the configuration techniques for using NetBeans for cross-platform Java development on Linux systems. By correctly configuring the JDK path, creating Java projects, writing code, running programs and debugging, readers can develop Java projects more efficiently. NetBeans provides a series of powerful functions and tools to help developers improve development efficiency and code quality.
