怎么用java编写一个按钮界面

新建一个窗口，然后实现一个关闭按钮”窗口的功能

import java.awt.*;

import java.awt.event.*;

public class TestWindowEvent {

public static void main (String[] args) {

new Frame88 ("WindowAdapter");

}

}

class Frame88 extends Frame {

Frame88 (String s) {

super(s);

setBounds (300,300,200,70);

setLayout (null);

setVisible (true);

addWindowListener (new WindowAdapter() {

public void windowClosing(WindowEvent e) {

setVisible (false);

System.exit(0);

}

}  );

} 

}

如何运java制作一个美丽的界面

可以用下面的代码放在界面所在的构造函数内,便出现美丽的Nimbus界面风格.

至于具体的界面呢.就看你的天分了...

try { UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");//Nimbus风格，新出来的外观，JDK 6 Update10 版本开始出现

} catch (Exception e) {

}
