java窗体中的textbox事件

为什么运行后我在text1里输入sun,text3里不会出现太阳?import java.awt.*;
import java.awt.event.*;
public class Window extends Frame implements ActionListener{

TextField text1,text2,text3;
Window(String s){
super(s);
text1=new TextField(8);

text2=new TextField(8);
text2.setSize(50, 20);

                  text3.setSize(50,20);
text1.addActionListener(this);
text2.addActionListener(this);
add(text1);
add(text2);
add(text3);

setSize(500,450);
setVisible(true);
validate();
