JAVA:猜数字游戏!

问题:系统随机生成一个1-100的数,猜错进行提示,直到猜对为止,并记录猜对所用的次数!

代码:

package day;

import java.util.Scanner;
import java.util.Random;
public class Day0401 {
public static void main(String[] args) {
	// TODO Auto-generated method stub
	Random random = new Random();
	int guess1 = 10 + random.nextInt(100);
	System.out.println("guess1 = " + guess1);
	int guess2 = 10 + (int)(Math.random()*91);
	System.out.println("guess2 = " + guess2);
	Scanner sc = new Scanner(System.in);
	int count = 0;
	while((guess1>0)&&(guess1<100)){
		System.out.println("please input a number:"); 
		int a = sc.nextInt();
	    count += 1;
	    if(guess1 < a) {
	    	System.out.println("猜大了!");
	    }else if(guess1 > a) {
	    	System.out.println("猜小了!");
	    }else {
	    	System.out.println("猜对了!");
	    	break;
	    }
	}
	System.out.println("你猜对一共用的次数是:"+ count);  
}

}
