java代码数组猜数游戏

如何用Java语言实现猜数字游戏

java实现的简单猜数字游戏代码,通过随机数与逻辑判断来实现游戏功能 代码如下： import java.util.InputMismatchException; import java.util.Scanner; public class Main { public static void main(String[] args) { // 产生一个随机数 int n

用java编写一个猜数字游戏,

import?java.util.Scanner;

//猜字符游戏

public?class?GuessingGame?{

//主方法

public?static?void?main(String[]?args)?{

Scanner?scan?=?new?Scanner(System.in);

int?count?=?0;?//猜错的次数

char[]?chs?=?generate();?//随机生成的字符数组

System.out.println(chs);?//作弊

while(true){?//自造死循环

System.out.println("猜吧!");

String?str?=?scan.next().toUpperCase();?//获取用户输入的字符串

if(str.equals("EXIT")){?//判断str是否是EXIT

System.out.println("下次再来吧!");

char[]?input?=?str.toCharArray();?//将字符串转换为字符数组

int[]?result?=?check(chs,input);?//对比

int?score?=?chs.length*100?-?count*10;?//一个字符100分,错一次减10分

System.out.println("恭喜你猜对了,得分:"?+?score);

break;?//猜对时跳出循环

}else{?//没猜对

count++;?//猜错次数增1

System.out.println("字符对:"+result[1]+"个,位置对:"+result[0]+"个");

public?static?char[]?generate(){

char[]?letters?=?{?'A',?'B',?'C',?'D',?'E',?'F',?'G',?'H',?'I',?'J',

'K',?'L',?'M',?'N',?'O',?'P',?'Q',?'R',?'S',?'T',?'U',?'V',

'W',?'X',?'Y',?'Z'};

boolean[]?flags?=?new?boolean[letters.length];?//1.

for(int?i=0;ichs.length;i++){

int?index;

do{

chs[i]?=?letters[index];

return?chs;

//对比随机数组与用户输入的数组

public?static?int[]?check(char[]?chs,char[]?input){

for(int?j=0;jinput.length;j++){

if(chs[i]==input[j]){?//字符对

result[1]++;?//字符对个数增1

if(i==j){?//位置对

result[0]++;?//位置对个数增1

return?result;
