java按钮实现页面跳转

假如有两个frame,分别为frame1,frame2,frame1加个按钮实现跳转.frame1代码如下
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class frame1 extends JFrame implements ActionListener{

    /**
     * @param args
     */
    private JButton jb;
    public frame1()
    {
        this.setSize(300, 200);
        this.setLocation(300, 400);
        jb=new JButton("跳转");
        this.add(jb);
        jb.addActionListener(this);//加入事件监听
        this.setVisible(true);
        
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
           frame1 frame=new frame1();
           
    }
    @Override
    public void actionPerformed(ActionEvent e) {
        // TODO Auto-generated method stub
        if(e.getSource()==jb)
        {
            this.dispose();//点击按钮时frame1销毁,new一个frame2
            new frame2();
        }
    }

}

frame2是个单纯的界面
import javax.swing.JButton;
import javax.swing.JFrame;

public class frame2 extends JFrame{

    /**
     * @param args
     */
    public frame2()
    {
        
        this.setSize(300, 200);
        this.setLocation(300, 400);

this.setVisible(true);
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
          frame2 frame=new frame2();
    }

}
