java实现猜数字小游戏（1-100）

import java.util.Scanner;public class GuessNumber {public static void main(String[] args){ Scanner sc = new Scanner(System.in);System.out.println("现在开始游戏？(Y/N)");String choice = sc.nextLine();while((!choice.equals("Y"))&&(!choice.equals("N"))){System.out.println("输入有误请重新输入：");choice = sc.nextLine();}if(choice.equals("N")){System.out.println("已退出");System.exit(0);}int number;int times = 1;while(true){int target = (int) (Math.random()*100+1);System.out.println("游戏已开始，请输入猜想的数字(1-100): ");number = sc.nextInt();while(true){if(number>target){System.out.println("猜大了！");number = sc.nextInt();times = times + 1;}if(number<target){System.out.println("猜小了！");number = sc.nextInt();times = times + 1;} if(number==target){System.out.println("猜对了！本次猜对所用次数为"+times+"次");times = 1;break;}}System.out.println("是否要继续游戏？(Y/N)");Scanner sc1 = new Scanner(System.in);choice = sc1.nextLine();if(choice.equals("N")){System.out.println("已退出");break;}}}}
