效果图：

 代码：

import java.util.Random;
import java.util.Scanner;

public class Guess {
    public static void main(String[] args) {
        //随机数的生成
        Random r = new Random();
        //1-100
        int  b= r.nextInt(100)+1;  //b是正确答案
        //获取键盘输入
        Scanner sc =new Scanner(System.in);
        //for死循环
        for ( int max=100,min=1;;){
            System.out.println("请在"+min+"--"+max+"输入你猜的数字");
            int  a= sc.nextInt();    //a是猜的值
            //进行判断
            if (a==b){
                System.out.println("正确");
                break;  //跳出循环
            }else if(a>b){
                if(a<max){
                    max=a;
                    System.out.println("猜大了");
                }else {
                    System.out.println("猜大了");
                }

            }else {
                if(a>min){
                    min=a;
                    System.out.println("猜小了");
                }else {
                    System.out.println("猜小了");
