JAVA + WeatherWebService realizes weather forecast interface call

Two steps to complete the interface call

The first step: import jar package

1. Online jar package
2. If the online jar package fails, just message me privately.

Step 2: Create a class implementation

1. Create a java class in your JAVA project (mine is: WeatherUtil)
2. Modify the cityid in the class to the region id you need to display, mine is Shanghai [ cityid query ]

WeatherUtil class code:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.SocketTimeoutException;
import java.net.URL;
import java.net.URLConnection;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import net.sf.json.JSONObject;
