用java实现猜数字游戏

import java.util.Scanner;

class GassNumber{

public static void main(String[] args){

    Scanner scan = new Scanner(System.in);
    
    System.out.println("请输入你的名字");
    
    String name = scan.next();
    
    System.out.println(name + "！我可以和你玩猜数字游戏");
    
    System.out.println("请输入10到99之间的整数");
    
    int x1 = scan.nextInt();
    int count = 1;//用的是do-while所以第一次猜数也算
    
    int num = (int)(Math.random() * 90 + 10);
    
    do{
        if(x1 > num){
           System.out.println("猜大了");
        }
        else if(x1 < num){
            System.out.println("猜小了");
        }
        
        count ++;
        
        x1 = scan.nextInt();
        
    }while(num != x1);
    
    System.out.println("恭喜你只用了" + count + "次就猜对了！");
}
}

运行结果：
