完整代码完全是按你要求写的。\x0d\x0aimport java.awt.Container\x0d\x0aimport java.awt.event.ActionEvent\x0d\x0aimport java.awt.event.ActionListener\x0d\x0aimport javax.swing.JButton\x0d\x0aimport javax.swing.JFrame\x0d\x0aimport javax.swing.JLabel\x0d\x0aimport javax.swing.JPanel\x0d\x0apublic class TESTswing extends JPanel implements ActionListener{\x0d\x0a \x0d\x0a JPanel p1 = new JPanel()\x0d\x0a JPanel p2 = new JPanel()\x0d\x0a JPanel p3 = new JPanel()\x0d\x0a JButton btn1 = new JButton("Button1")\x0d\x0a JButton btn2 = new JButton("Button2")\x0d\x0a public TESTswing()\x0d\x0a {\x0d\x0a p1.add(btn1)\x0d\x0a p1.add(btn2)\x0d\x0a p2.add(new JLabel("I’m is p2"))\x0d\x0a p3.add(new JLabel("I’m is p3"))\x0d\x0a \x0d\x0a p2.setVisible(false)\x0d\x0a p3.setVisible(false)\x0d\x0a this.add(p1)\x0d\x0a this.add(p2)\x0d\x0a this.add(p3)\x0d\x0a btn1.addActionListener(this)\x0d\x0a btn2.addActionListener(this)\x0d\x0a }\x0d\x0a public static void main(String[] args) {\x0d\x0a \x0d\x0a JFrame frame = new JFrame()\x0d\x0a frame.setSize(200, 200)\x0d\x0a \x0d\x0a Container contentPane = frame.getContentPane()\x0d\x0a contentPane.add(new TESTswing())\x0d\x0a frame.show()\x0d\x0a }\x0d\x0a public void actionPerformed(ActionEvent e) {\x0d\x0a // TODO Auto-generated method stub\x0d\x0a String cmd = e.getActionCommand()\x0d\x0a \x0d\x0a if (cmd.equals("Button1"))\x0d\x0a {\x0d\x0a \x0d\x0a p2.setVisible(true)\x0d\x0a p3.setVisible(false)\x0d\x0a \x0d\x0a }\x0d\x0a else\x0d\x0a { \x0d\x0a p2.setVisible(false)\x0d\x0a p3.setVisible(true)\x0d\x0a }\x0d\x0a }

按照你的要求添加两个按钮的Java程序如下:

package com.sunshine.customer

import java.awt.*

import java.awt.event.*

import javax.swing.*

import javax.swing.table.DefaultTableModel

public class JTableDemo extends JFrame implements ActionListener{

private JPanel topPanel

private JTable table

private JButton addRoom=new JButton("添加房间")

private JButton removeRoom=new JButton("删除房间")

private DefaultTableModel dtm
