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(); 
} 

}
