一个小问题？教教初学者吧！给分

import java.awt.*;
import java.awt.event.*;
public class KeyEventTest extends Frame {
private TextArea msgArea;


public static void main(String args[]) {
KeyEventTest test=new KeyEventTest();
test.setSize(300,300);
test.setVisible(true);
}


public KeyEventTest() {
msgArea=new TextArea();
msgArea.setEnabled(false);//让Button取得控制权
add(msgArea,BorderLayout.CENTER);
Button b=new Button("test");
b.addKeyListener(new KeyListen(this));//让Button能够处理KeyEvent
add(b,BorderLayout.SOUTH);
}


public void ShowMessage(String str) {
msgArea.append(str+"\n");
}
}


class KeyListen implements KeyListener {//用来接收KeyEvent的类
private KeyEventTest parent;

public KeyListen(KeyEventTest p) {
parent=p;
}

public void KeyPressed(KeyEvent e) {
}


public void KeyReleased(KeyEvent e) {
parent.ShowMessage("Key char=" + e.getKeyChar());
parent.ShowMessage("Key code=" + e.getKeyCode());
parent.ShowMessage("modifier=" + e.getModifiers());
}

public void KeyTyped(KeyEvent e) {
}
}
这个程序该怎样改正确？我使用的是JDK帮忙解决给分！！

好困呀

public KeyListen(KeyEventTest p) {

}

public void keyPressed(KeyEvent e) {
}


public void keyReleased(KeyEvent e) {
parent.ShowMessage("Key char=" + e.getKeyChar());
parent.ShowMessage("Key code=" + e.getKeyCode());
parent.ShowMessage("modifier=" + e.getModifiers());
}

public void keyTyped(KeyEvent e) {
}
}

你那三个事件，keyTyped什么的写成KeyTyped了，大小写错了，看看编译器提示吧
