利用java制作一个猜数字小游戏

package com.swift;import java.util.Random;import java.util.Scanner;public class GuessBigSmall { public static void main(String[] args) { Scanner scan=new Scanner(System.in); Random random = new Random(); int number = random.nextInt(1000) + 1; for (;;) { System.out.println("请输入猜的——正整数——数字："); int guessNumber=scan.nextInt(); if (guessNumber>number) { System.out.println("猜大了。"); continue; } else if (guessNumber<number) { System.out.println("猜小了。"); continue; } else { System.out.println("恭喜，猜对了。"); break; }  } }}
