选项卡问题，请教一下各位。
创建一个类A继承JFrame,在A的构造方法中添加了几个选项卡组件（a,b,c,d),我再选项卡a中加了一个button按钮，我想点击button按钮，选项卡会从当前a跳到选项卡b.请教一下代码应该怎么写？



补充：选项卡（a,b,c,d)在同一个界面中。

------解决方案--------------------
package jfrm;

import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.*;

public class Jfrm extends JFrame implements MouseListener{
 
 JButton[] jB1 = {new JButton("欢迎页"), new JButton("欢迎页")};
 JButton[] jB2 = {new JButton("人员管理"), new JButton("人员管理")};
 JButton[] jB4 = {new JButton("人员管理"), new JButton("人员管理")};
 JTabbedPane jTP = new JTabbedPane();
 JPanel jP4 = new JPanel(); 
  
 public Jfrm()
 {
setSize(500, 400);
setDefaultCloseOperation(EXIT_ON_CLOSE);
  
JPanel[] jP1 = {new JPanel(), new JPanel()};
jP1[0].setLayout(new FlowLayout());
jP1[1].setLayout(new FlowLayout());
jP1[0].add(jB4[0]);
jP1[1].add(jB4[1]);
jB4[0].addMouseListener(this);
jB4[1].addMouseListener(this);
  
JPanel[] jP2 = {new JPanel(), new JPanel()};
jP2[0].setLayout(new BorderLayout());
jP2[1].setLayout(new BorderLayout());
jP2[0].add(jB1[0]);
jP2[1].add(jB2[1]);
  
JPanel jP3 = new JPanel(); 
jP3.setLayout(new BorderLayout());
jP3.add("West", jP1[0]);
jP3.add(jP2[0]);
  
jP4.setLayout(new BorderLayout());
jP4.add("West", jP1[1]);
jP4.add(jP2[1]);
  
jTP.add("欢迎页", jP3);
jTP.add("人员管理", jP4);
add(jTP);
  
setVisible(true);
 }
 
 public static void main(String[] args) {
new Jfrm();
 }

 public void mouseClicked(MouseEvent e) {
// TODO Auto-generated method stub
  
 }

 public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
  
 }

 public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
  
 }

 public void mousePressed(MouseEvent e) {
if (e.getSource() == jB4[0] || e.getSource() == jB4[1])
{
jTP.setSelectedComponent(jP4) ;
}
 }

 public void mouseReleased(MouseEvent e) {
// TODO Auto-generated method stub
  
 }

}
这段代码对你应该有帮助你可以自己调试下
