import java.util.Random; import java.util.Scanner; public class xiaogame { private int num; public int createRandom(){ Random r=new Random(); //Random类中有个nextInt（）方法可随机产生一个随机整数 num=r.nextInt(100); return num; } public void compare(){ Scanner sc=new Scanner(System.in); System.out.println("请输入一个要比较的整数："); int a=sc.nextInt(); if(num>a){ System.out.println("输入的数太小请重新输入一个数："); compare(); //递归调用 }else if(num<a){ System.out.println("输入的数太大请重新输入一个数："); compare(); //递归调用 }else{ System.out.println("恭喜您猜对了"); } } public static void main(String[] args) { xiaogame xg=new xiaogame(); xg.createRandom(); xg.compare(); } }
