java代码实现猜数字游戏

public class GuessingGame {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int num = (int)(Math.random()*1000+1); //藏起来的数
System.out.println(num); //作弊

int guess;
do{
System.out.println("猜吧!");
guess = scan.nextInt(); //1/3

if(guess==0){
break;
}else if(guess>num){
System.out.println("太大了");
}else if(guess<num){
System.out.println("太小了");
}
}while(guess!=num); //2.
if(guess==num){
System.out.println("恭喜你，猜对了!");
}else{
System.out.println("下次再来吧!");
}

/*

System.out.println("猜吧!");
