Java语言程序设计(基础篇)编程练习题7.35---------------------------------------------------------------------

忘了把题目附上了........便于一贴式服务
代码还有改进空间，比如if(Arrays.equals(fG, finalGuess) && (c[0] != i))和前面的int i =1； 里的i就是多余的
题目：7.35（游戏：猜字游戏）编写一个猜字游戏。随机产生一个单词，提示用户一次猜测一个字母，如运行示例所示。单词中的每个字母显示为一个星号。当用户猜测正确后，正确的字母显示出来。当用户猜出一个单词，显示猜错的次数，并且询问用户是否据需对另外一个单词进行游戏。声明一个数组来存储单词，如下所示：String[] words = {"tom", "help", "black", ........};
(guess) enter a letter in word ***** > b
(guess) enter a letter in word b**** > l
(guess) enter a letter in word bl*** > b
b is already in the word
(guess) enter a letter in word bl*** > a
(guess) enter a letter in word bla** > n
n is not in the word
(guess) enter a letter in word bla** > k
(guess) enter a letter in word bla*k > c
the word is black. you missed 1 time
do you want to guess another word? enter y or n>
n
