用java编写一个猜数字游戏，

package day06;

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!");

break;

}

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

int[] result = check(chs,input);  //对比

if(result[0]==chs.length){ //位置对为5

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");

}

}

}

//随机生成5个字符数组

public static char[] generate(){

char[] chs = new char[5];

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{

index = (int)(Math.random()*letters.length); //0到25

}while(flags[index]==true); //2.

chs[i] = letters[index];

flags[index] = true; //3.

}

return chs;

}

//对比随机数组与用户输入的数组

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

int[] result = new int[2];

for(int i=0;ichs.length;i++){

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

}

break;

}

}

}

return result;

}

}

java猜数字游戏怎么怎么做到在游戏结束后输入y重新开始输入n退出游戏？下面是源代码

while(true){

//你的程序

System.out.println("再玩一次？");

String st= scan.next();

if( st=="y")｛continue;｝

if( st=="n")｛break;｝

System.out.println("既不是y也不是n，出错");

}

java猜数字小游戏代码怎么写？

import java.util.Scanner;

public class Guess {

private static final int F = 1;

private static final int T = 100;

public static void main(String[] args) {

int num = (int)(Math.random() * T) + F;

Scanner s = new Scanner(System. in );

// 初始化

int guest = -1;

while (true) {

System.out.print("请输入你猜测的数字(" + F + "-" + T + ")：");

// 每次输入的值，采纳即可

guest = s.nextInt();

if (guest  num) {

System.out.println(F + "--" + guest);

} else if (guest  num) {

System.out.println(guest + "--" + T);

} else {

System.out.println("中奖了");

break;

}

}

s.close();

}

}
