我已经做了一个刽子手的人，它基本上是完整的但是我似乎无法得到一个循环工作，所以当一个用户赢了他们被问到他们是否想要另一个游戏，如果他们说是，那么它再次开始？谁能帮助我？

我试过了吗？
if (mask.contains(words[selectA])) {
System.out.println("You win!");
System.out.println("would you like another game?");
loop = scan.next();
while ("Yes".equals(loop) ||"yes".equals(loop));
}
什么都没发生。
答案 0 :(得分：1)
最简单的方法是这样的：
if("Yes".equals(loop) || "yes".equals(loop)) {
new Game(words, scanner);
}
或者如果玩家再次选择等级更好，你应该在Hangman类中放置一个真正的循环（你必须改变它：
if(hangman == true) { <- why there was while ??
System.out.println("You lose!");
//System.exit(0); <- remove this
}
并允许Game类完成，返回Hangman类，所有代码都应该在循环中（仅在用户想要退出时结束）。试试这个并询问是否有任何问题。
