How to utilize the Swing look and feel framework?

To utilize Swing’s look and feel framework, you can follow these steps:

1. Download and import jar files of beautification frameworks, such as Substance, FlatLaf, etc. They can be downloaded from official websites or third-party library websites.
2. Create a main class in your Swing project, for example Main.java.
3. In the main method of the main class, set the LookAndFeel to the class name of the GUI framework you want to use. For example, for the Substance framework, you can use the following code:

import javax.swing.UIManager;

public class Main {
    public static void main(String[] args) {
        try {
            // 设置Substance美化框架
            UIManager.setLookAndFeel("org.pushingpixels.substance.api.skin.SubstanceGraphiteLookAndFeel");
        } catch (Exception e) {
            e.printStackTrace();
        }
        
        // 启动你的Swing应用
        // ...
    }
}

1. To compile and run your Swing application, you should be able to see the interface using the selected look and feel framework.

Before using a GUI framework, make sure you have correctly imported the necessary jar files and set the correct LookAndFeel class name in your code. Additionally, different GUI frameworks may have different class names and usage methods, so refer to the documentation or sample code of the specific framework.
