import java.util.Random;import java.util.Scanner;public class GuessNumber {    public static void main(String[] args) {        Random a = new Random();        System.out.println("系统已将完成随机数字的生成！");        int randomNum = a.nextInt(100);        Scanner b = new Scanner(System.in);        System.out.println("请输入你要猜的数字：");        int inputNum = b.nextInt();        while (randomNum != inputNum){            if (inputNum >randomNum){                System.out.println("对不起猜的太大了，请继续输入……");            }else {                System.out.println("对不起猜的太小了，请继续输入……");            }            System.out.println("请输入你要猜的数字：");            inputNum = b.nextInt();        }        System.out.println("恭喜你，猜对了！");    }}
