java: keyListener を使用したときに、型 Pong.Move1 が継承された抽象メソッド KeyListener.keyTyped(KeyEvent) を実装する必要があります。意味がわからない？ヘルプ？
これが私が問題を抱えているスレッドです...
private class Move1 extends Thread implements KeyListener{
public void run(){
addKeyListener(this);
while(true){
//hitRight makes you lose.
//point is how many times it ricochets.
if(ball.intersects(borderRight)){
hitRight = true;
}
if(ball.intersects(borderLeft)){
point++;
}
}
}
public void keyPressed(KeyEvent event){
while(event.getKeyCode()==40||event.getKeyCode()=='s'){
direction = DOWN;
Thread.sleep(500);
}
}
public void KeyReleased(KeyEvent event){
}
public void KeyTyped(KeyEvent event){
}
}
私も自分のThread.sleep(500);ラインで立ち往生しています。Unhandled例外タイプ InterruptedExceptionと表示されます。何か助けはありますか？どうも。
あ、何か忘れてました。
1:実行しようとすると、次のエラーのみ
Exception in thread "main" java.lang.Error: Unresolved compilation problem: at Pong.main(Pong.java:50)が表示されます。それがpublic static void main(String[] args)ラインです。私の完全なコードは最後にあるので、それを見ることができます (plz)
2: 私は eclipse を使用しています。
3：私は基本的に初心者です（そうではありません）
