可能重复：
Java hangman game with gui, problems with incrementing/decrementing numbers的Java Swing刽子手比赛赢/记不清不起作用，KeyListener的是越野车
所以问题是，我吸在摇摆，不知道如何使用keylistener，它开始多次听按键（第二游戏后记录2个键，第三游戏后记录3个键等等）。我不知道如何正确使用Event Dispatch Thread，或者我应该使用它，并且won/lost count错误地增加。此外，当我希望框架听取键盘输入时，我要求将其焦点放在窗口中，但当我不希望框架读取键盘输入时，我不知道如何解除它。欢迎任何帮助。这是我第二次提出这个问题，希望这次我已经让程序和问题更容易理解了。编辑：游戏现在可以工作，还可以添加缓冲写入器来写入日志文件。对不起，懒得修改一些代码的命名部分为英文，因为他们是立陶宛人。

我敢打赌，您每次开始游戏时都会注册新的关键人物，同时保留年长的听众。也就是说，如果你想回答，你应该尝试发布一个[SSCCE]（http://sscce.org） – SJuan76
