Java 如何以及在何处实现if/else语句

我几乎完成了用Java创建一个刽子手游戏，尽管我在最后一部分遇到了困难。我想让程序检查单词的所有字母是否猜对了，如果猜对了，游戏会打印一条消息说他们赢了，游戏结束，程序进入主类中的do-while循环，询问他们是否愿意再次玩。然而，如果不是这样，游戏将一直持续到这一点，或者如果已经使用了所有5次猜测，那么游戏将再次发送到do while循环，以便重新启动游戏，而不是简单地终止程序

问题是我不确定如何以及在何处构造if和else语句，以便这样做

任何帮助将不胜感激，如果我可以提供进一步的信息，以帮助缩小任何东西，请问太多，提前谢谢你

我是这么看的。调用

myHangman.compute（）之后，您要检查玩家是否赢得游戏或耗尽生命。每个测试都是使用
if
表达式的单独测试。没有
else
部分，因为如果测试失败，游戏就会继续

如果识别出其中一个条件，则您希望显示一条消息，然后您希望退出当前游戏循环，以便询问用户是否要玩另一个游戏。方法是使用
break
语句

一个问题是，在主游戏循环中，如果用户猜到了整个单词，您无法询问
Hangman
类。要做到这一点，您可以将此方法添加到
Hangman
类的底部：

public boolean getAllLettersFound() {
    return outputWord.indexOf('*') < 0;
}

应该这样做。快乐编码
 非常感谢你的工作，就像一个魅力，快乐的编码也！
