我的问题是，目前我正在为游戏制作GUI，这个GUI有很多按钮。我之前在我的代码中遇到了一个问题，我使用的actionListener是快速连续地在两个按钮中查找事件，没有足够的时间让第二个按钮执行和操作并使其无用。我认为通过在内部类中使第二个按钮成为不同的actionListener来克服这个问题
button5.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
现在我正在尝试为第三个按钮做同样的事情（最后是第四个和第五个按钮
P1Roll.addActionListener(new ActionListener(){
public void ActionPerformed(ActionEvent e){
但它给我带来了各种各样的错误。由于我不熟悉，我不确定如何继续。任何关于此的提示或我的代码中的任何内容都将非常感激。 :)

答案 0 :(得分：0)
从最初阅读代码开始，您似乎正在使用不正确的语法创建匿名ActionListener。
P1Roll.addActionListener(new ActionListener(){ public void ActionPerformed(ActionEvent e){
}
@Override
public void actionPerformed(ActionEvent e) {
int turnNum;
for(turnNum; numTurns > 0 ; numTurns -- ){
}
}});
应该是
P1Roll.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e)
{
int turnNum;
for(turnNum; numTurns > 0 ; numTurns -- )
{
}
});
