首页窗口类

package com.beyole.util;

import java.awt.BorderLayout;

import java.awt.GridLayout;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JButton;

@SuppressWarnings("serial")

class win3 extends JFrame implements ActionListener {

@SuppressWarnings("unused")

private JButton btBlue, btDialog;

public win3(){

this.setTitle("同学录管理系统");//设置标题

JPanel south = new JPanel(new GridLayout(1,10,9,10));

south.add(new JButton ("登录"));//点击事件

this.setResizable(false);//关闭当前界面

south.add(new JButton ("开发团队"));//点击事件

this.setResizable(false);//关闭当前界面

this.add(south, BorderLayout.SOUTH);

this.setResizable(false);//不可改变大小

this.setLocationRelativeTo(null);//居中显示

this.setSize(400, 400);//窗体大小

this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//默认关闭操作

}

private static void win2(boolean b) {

// TODO Auto-generated method stub

}

public static void main(String[] args) {

new win3().setVisible(true);

}

@Override

public void actionPerformed(ActionEvent e) {

// TODO 自动生成的方法存根

}

public JButton getBtBlue() {

return btBlue;

}

public void setBtBlue(JButton btBlue) {

this.btBlue = btBlue;

}

}

第B类按钮部分

public win2()

{

super("同学录管理系统菜单");

//框架中加载面板

pan p =new pan();

this.add(p);

Font d=new Font("宋体",Font.BOLD,100);

JPanel south = new JPanel(new GridLayout(2,2,2,2));

south.add(new JButton ("浏览"));

south.add(new JButton ("查找"));

south.add(new JButton ("增加"));

south.add(new JButton ("删除"));

south.add(new JButton ("退出"));

south.add(new JButton ("返回上一级"));

this.add(south, BorderLayout.SOUTH);

}如何A跳转到第B类窗口呢？
