-----------------------服务接口--------------------------

package ch09.server;

import java.util.Random;

public class WeatherImpl implements Iweather {//实现随机数接口的类 返回1-15的随机数 public int getRandom() {  Random rand=new Random();  int radom=rand.nextInt(16);//产生1~16的整数nextInt(100)时返回0-99  return radom; }
