猜数字游戏

电脑自动生成1~100之间的整数，键盘输入猜数字

import java.util.Scanner;public class GuessNum{public static void main(String[] args){int goalNum = 1 + (int)(Math.random()*100);Scanner s = new Scanner(System.in);int guessNum;while (true){System.out.println("请输入一个1~100的整数：");guessNum = s.nextInt();if (guessNum == goalNum) {System.out.println("猜中了");break;}else {System.out.println("没猜中！" + ( (guessNum - goalNum) > 0 ? "高了" : "低了")  );}}}}
