Java中的刽子手游戏
Hangman是一种流行的猜词游戏，玩家通过一次推测一个字母来努力构建一个丢失的单词。经过一定数量的偏离基地猜测后，游戏结束，玩家输了。当玩家准确区分丢失单词的所有字母时，游戏也会结束。下面给出了这个游戏在Java中的实现。
例子：
Output:
Welcome to HANGMAN GAME
let’s play the game
_ _ _ _ _ _
Your Guess:
Input: s
Output:
S is not present in the word.
_ _ _ _ _ _
You have 4 guesses left.
Your Guess:
Input: m
Output:
M is not present in the word.
_ _ _ _ _ _
You have 3 guesses left.
Your Guess:
Input: d
Output:
D is not present in the word.
_ _ _ _ _ _
You have 2 guesses left.
Your Guess:
Input: t
Output:
T is present in the word.
T_ _ _ T_
You have 2 guesses left.
Your Guess:
Input: o
Output:
O is present in the word.
TO_ OT_
You have 2 guesses left.
Your Guess:
Input: y
Output:
Y is present in the word.
TOYOT_
You have 2 guesses left.
Your Guess:
Input: a
Output:
A is present in the word.
The word is: TOYOTA
Well Played, you did it!!
Java是一种通用的计算机编程方言，它是并发的、基于类的、面向对象的，并且专门设计为具有尽可能少的依赖关系。 Java为随机数提供了一个完整的库，以了解它在日常编程中的重要性。 本文的代码中使用了 nextInt()函数。这个游戏适合初学者学习用Java编写代码，并向他们简要介绍如何使用字符串、循环和条件语句。
了解游戏
玩家必须猜出一个词。因此，输出屏幕将显示代表要猜测的字母的破折号数。然后玩家会猜出一个字母。如果该字母出现在单词中，则程序将在它出现的每个位置用该字母替换破折号。如果单词中不存在该字母，那么生命线的数量就会减少（由有限的机会组成）。一旦单词的所有字母都猜对了，玩家就赢得了游戏。
比赛计划：
用户应该首先猜测单词中出现次数最多的字母是元音（ a , e , i , o , u ）。除了元音，其他最常用的字母是t 、 n 、 s 、 h 、 r 、 d和l 。
游戏的实现
在程序中，创建了一个类游戏，其中创建了一个由单词组成的字符串列表。在单词列表中，将使用随机模块（Java.util.Random）随机选择一个单词，供用户猜测其字母。选择单词后，使用 toUpperCase()函数将所有字母变为大写，然后将这些字母替换为破折号。游戏中允许的最大猜错次数为5 ，如果用户超过该次数，则用户将输掉游戏。在 while 循环中，当用户开始猜测字母时，正确的猜测将用正确的字母替换破折号，而错误的猜测会将计算错误猜测次数的变量增加1 。
- 第一个条件用于通知用户当用户猜错字母时剩余的生命线。
- 第二个条件用于告诉用户输入的字母已经被猜到了。
- 第三个条件是检查猜测的新字母是否存在于单词中，如果它们正确则将破折号替换为那些正确的字母
- 如果单词中不存在该字母，则生命线减 1。
如果满足以下任一条件，则游戏结束：
- 用户已正确猜出整个单词。
- 用户的生命线已经结束。
