java----猜字符小游戏

刚学了方法，做了个小项目，猜字符小游戏，这里和大家分享一下。
我们通过要达到的效果来分析：

            1首先命令行窗口提示用户进入猜字符游戏，并显示“猜吧”            2然后用户输入一个五位数的字符串（不能重复），接着系统进行判断            3如果字符串为"EXIT"则退出游戏            4如果没猜对则提示猜对的字符的个数和猜对位置的个数            5如果猜对则给出分数，并退出游戏            6分数的话是一个字符一百分，猜错一次扣十分。我们来分析：这个游戏需要用到哪些数据：    1.char[] ch 用来接收系统产生的随机字符    2.char[] input 用来接收用户输入的字符    3.int score 用来接收分数    4.int count 用来接收猜错次数    5.int[] result 用来存放猜对个数和猜对位置个数 定义方法：   1. public static char[] generate（）{//用来生成随机字符数组                            char[] ch = new char[5];                            ...                            return ch;        }    2.public static int[] check(char[] ch,char[] input){//用来检查猜中几个和猜中位置情况                            int[] result = new int[ch.length]；                            ...                            return result;    }    代码如下：   1. public static char[] generate（）{                            char[] letter = new char[26]；//用来存放A-Z的字符                            for（int i =0;i<letter.length;i++）{                                        letter[i]=（char）（i+65）;//将字母对应编码强制转换为字符并存放在数组中                            }                            int index = 0；                            boolean[] flag = new boolean[letter.length];//用来标记已经选过的字符                            char[] ch = new char[5]；                            while（index<ch.length）{                                             int i = （int）（Math.random（）*letter.length）；                                             if（flag[i]）{//排除已经选过的字符                                                     contiune;                                             }                                             ch[index]=letter[i];                                             index++;                                             flag[i]=true;                            }                            return ch;        }        2.public static in[] check（char[] ch,char[] input）{                                int[] result = new int[2];                                for（int i= 0；i<ch.length;i++）{                                            for（int j=0;j<input.length;j++）{                                                        if（ch[i]==input[j]）{                                                                result[0]++;//猜中字符的个数                                                                if（i==j）{                                                                        result[1]++;//猜中位置的个数                                                                        break;//如果位置判断相同则不用扫描后面的字符了                                                                }                                                        }                                            }                                }                                return result;             }             接下来开始写main函数             public static void main（String[] agrs）{                                 char[] ch = generate（）;                                 Scanner sc =new Sacnner（System.in）;                                 int count =0；                                 int score =0；                                 System.out.println("欢迎来到猜字符游戏")；                                 while（true）{                                                System.out.println（"猜吧"）                                                String str = sc.nextInt（）.touppercase（）;//把输入的字符串转换为大写                                                if（str.equal（"EXIT"））{                                                            System.out.println（"退出"）；                                                            break；                                                }                                                char input = str.toCharArrays（）;//字符串转换为字符数组                                                int result = check（ch,input）;                                                if（result[1]==ch.length）{                                                        score = 100*ch.length-10*count；                                                        System.out.println（"猜对了，得分："+score）                                                        break;                                                }                                                else{                                                            System.out.println（"猜对字符个数为"+result[0]+"猜对字符位置个数为"+result[1]）;                                                            count++;                                                }                                 }             }             这个游戏还可以加些小功能，比如通过改变猜测的字符串的长度来改变游戏难度，或者通过分数来限制游戏猜测次数等等，这里就不多写了，大家可以尝试下。
