Use Swing to create GUI(图形用户界面)

一.程序入口

package p1;

import java.awt.Container;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class EnterClass
{
   public static void createGUI() {
       JFrame frame=new JFrame("阿冲");
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       Container contentPane=frame.getContentPane();
       contentPane.setLayout(new FlowLayout());

       contentPane.add(new JLabel("123"));

       frame.setSize(600,600);
       frame.setVisible(true);
   }

   public static void createGUI2() {
       //JFrame frame=new MyFrame("阿冲");//
//       JFrame frame=new MouseFrame("阿冲");
//       JFrame frame=new BarFrame("阿冲");
       JFrame frame=new DialogFrame("阿冲");
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

       frame.setSize(570,570);
       frame.setVisible(true);
   }

   public static void main(String[] args) {
       javax.swing.SwingUtilities.invokeLater(new Runnable() {
           @Override
           public void run()
           {
               //createGUI();
               createGUI2();
           }
       });
   }
}

二.自定义Frame

   }

   // 简单确认输入框
   private void test2() {
       int select = JOptionPane.showConfirmDialog(this, "是否确认删除?", "确认", JOptionPane.YES_NO_OPTION);

       if (select == 0) {
