我在编译时出错，这是为什么呀？代码如下：
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class p75_ex3 extends Applet
{TextField text1;TextArea text2;
public void init()
{text1=new TextField(12);
text2=new TextArea(10,20);
add(text1);add(text2);
text1.addActionListener(this);
text2.addTextListener(this);
}
public void actionPerformed(ActionEvent e)
{if(e.getSource()==text1)
{text2.append("\n"+text1.getText());
}
}
public void textValueChanged(TextEvent e)
{if(e.getSource()==text2)
{text1.setText("Hello,yichun university!");
}
}
}



//错误提示为：
p75_ex3.java:10: addActionListener(java.awt.event.ActionListener) in java.awt.TextField cannot be applied to (p75_ex3)
text1.addActionListener(this);
^
p75_ex3.java:11: addTextListener(java.awt.event.TextListener) in java.awt.TextComponent cannot be applied to (p75_ex3)
text2.addTextListener(this);
^

大家帮忙看一下吧！！

是不是少了接口啊
public class p75_ex3 extends Applet implements ActionListener

[whyman]

还有一个TextListener
public class p75_ex3 extends Applet implements ActionListener,TextListener
程序第四行
