如何实现对键盘事件的处理？（有程序）100分

[hujh82]

大家看看这个程序为什么编译通不过？？？？

import java.awt.*;
import java.awt.event.*;

class Tempt extends Frame
{
Tempt()
{
addKeyListener(this);
}

public void keyPressed(KeyEvent e)
{
System.out.println("e");
}
public void KeyReleased(KeyEvent e){System.out.println("e");}
public void KeyTyped(KeyEvent e){}
public static void main (String args[])
{
//System.out.println("Hello World!");
//System.out.flush();
System.out.println("Staring....");
Tempt t=new Tempt();
t.setSize(400,400);
t.setVisible(true);
}
}

如果不在GUI下写键盘的监听，该如何写，能这样写吗？

你的类没有实现KeyListener

实现KeyListener接口
class Tempt extends Frame implements KeyListener
{
//
}

程序改为：
import java.awt.*;
import java.awt.event.*;

class Tempt extends Frame implements KeyListener
{
Tempt()
{
addKeyListener(this);
}

public void keyPressed(KeyEvent e)
{
System.out.println(e);
}
public void keyReleased(KeyEvent e){System.out.println(e);}
public void keyTyped(KeyEvent e){}
public static void main (String args[])
{
//System.out.println("Hello World!");
//System.out.flush();
System.out.println("Staring....");
Tempt t=new Tempt();
t.setSize(400,400);
t.setVisible(true);
}
}

我没什么可说的了

[maowu]

import java.awt.*;
import java.awt.event.*;

// 加上这一部分
public class Tempt extends Frame implements KeyListener
{
Tempt()
{
addKeyListener(this);
}
public void keyPressed(KeyEvent e){
System.out.println("e");
}
// 这个k要小写。
public void keyReleased(KeyEvent e){System.out.println("e");}
public void keyTyped(KeyEvent e){}
public static void maifn (String args[])
{
//System.out.println("Hello World!");
//System.out.flush();
System.out.println("Staring....");
Tempt t=new Tempt();
t.setSize(400,400);
t.setVisible(true);
}
}

[qybao]

或者在类内部实现该接口
class Tempt extends Frame
{
Tempt()
{
addKeyListener(new KeyListener() {
public void keyPressed(KeyEvent e)
{
System.out.println("e");
}
public void KeyReleased(KeyEvent e){System.out.println("e");}
public void KeyTyped(KeyEvent e){}

});
}

public static void main (String args[])
{
//System.out.println("Hello World!");
//System.out.flush();
System.out.println("Staring....");
Tempt t=new Tempt();
t.setSize(400,400);
t.setVisible(true);
}
}
