import java.util.Random;
public class Guess { private Random random; public int GetRandomNum() { return random.nextInt(100); } public int JugeNum(int n,int num) { if(n>num){ return 1;} else if (n return 2; } else if (n==num) { return 0; } else { return -1; } } public Guess() { super(); random=new Random(); }
public String play(int num,int n) { if(JugeNum(num ,n)==0){ return "猜对了";} else if(JugeNum(num,n)==2){ return "大了";} else if(JugeNum(num,n)==1){ return "小了";} else if(JugeNum(num,n)==-1){ return "数据有误";} return "数据有误"; }

}
