Answer 1

try {
this.wait(500);
} catch (InterruptedException e2) { } jb[i].removeActionListener(this);
jb[i].setLabel(""); try {
this.wait(500);
} catch (InterruptedException e2) { }
把这段注掉就能正确运行了

Answer 2

这代码是用来等待0.5S的，如果注释掉，按钮不就会加入监听后马上被撤销监听啦？那是否有可以让它等待0.5S(期间继续监听)的调用呢？Timer不会用！恳请大侠指点

Answer 4

wait 之后好像是不是需要其他线程来唤醒啊！

Answer 5

我是 菜鸟。在你基础上最少的修改  添加了多线程。望采纳//灰常低级的打地鼠游戏
