json三层解析（数组解析）

里面多了数组，所以用到了JOSNArray

 package com.xykj.weather;

 import java.io.BufferedReader;
 import java.io.IOException;
 import java.io.InputStreamReader;
 import java.net.MalformedURLException;
 import java.net.URL;

 import net.sf.json.JSONArray;
 import net.sf.json.JSONObject;

 public class Weather {

     public static void main(String[] args) {

             URL url = new URL(
                     "http://apicloud.mob.com/v1/weather/query?province=%E6%B9%96%E5%8D%97&key=520520test&city=%E6%B2%85%E9%99%B5");
             try {
                 BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream()));
                 StringBuffer sb = new StringBuffer();
                 String st;
                 while ((st = br.readLine()) != null) {
                     sb.append(st);
                 }
                 System.out.println(sb.toString());
                 JSONObject first = JSONObject.fromObject(sb.toString());
                 System.out.println("============json解析第一层============");

                         System.out.println("===========未来天气============");
