首先要新建一个界面，在这里使用的是JFrame。首先创建一个基本的界面，要设置大小，而且JFrame默认是不显示的所以要使用setVisible(true)。
package DemoOfSwing;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
public class MainFrame extends JFrame{
public MainFrame() {
// TODO Auto-generated constructor stub
this.setSize(300, 300);
this.setVisible(true);
addWindowListener(new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});
}
public static void main(String argc[]) {
MainFrame mainFram = new MainFrame();
}
}
