按键 keyPressed抛异常！！！

code = -3
java.lang.IllegalArgumentException

代码如下 ：

public void keyPressed(int keyCode){
System.out.println("code = "+keyCode);;
int key = this.getKeyCode(keyCode);
System.out.println("key = "+ " :: code= ");


}

真不知道哪里错了问题了 忘各位大虾指正 谢谢

addKeyListener(new java.awt.event.KeyAdapter() {
public void keyPressed(java.awt.event.KeyEvent evt) {
System.out.println("code = "+evt.getKeyCode());
}
});

//你的这个那是键盘事件
public void keyPressed(int keyCode){

this.getKeyCode(keyCode);
这句话不对 getGameAction(int keyCode)跟getKeyCode(int gameAction)
不一样

[able_6]

那为什么会报错呢。。。 我就郁闷呢。。

[kf156]

int key = this.getKeyCode(keyCode);
你keyCode已经是键值了还去得键值...
应改为int key=getGameAction(int keyCode)

[JarodYv]

应该是getGameAction(int keyCode);

传入的参数 是非法参数， 哈哈
