主方法

package com.third;

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		GuessingNumbers gue = new GuessingNumbers();
		Scanner scan = new Scanner(System.in);
		gue.getNum();
		while(true){
			System.out.println("请选择操作");
			System.out.println("1.猜数字");
			System.out.println("2.查看猜测记录");
			System.out.println("3.偷看答案");
			int a = scan.nextInt();
			if(a==1){
				gue.inputNum();
			}
			else if(a==2){
				gue.printNum();
			}
			else if(a==3){
				System.out.println(gue.num);
			}
			if(gue.b==10)
				break;
			else if(gue.b==12){
				System.out.println("恭喜你猜对了！！！");
				break;
			}
