Java编程实现NBA赛事接口调用实例代码_开发_开发者

第一步：找别人提供的接口，比如在这里我选择的http://www.devze.com是聚合数据提供的接口

第二步：要申请相应的AppKey方可使用，此参数会作为接口的参数调用。

第三步：调用别人提供的接口方法

代码如下：

package juheapi.nba;
/**

import net.sf.json.JSONObject;
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.util.HashMap;
import java.util.Map;

在使用上述代码时可能会出现异常，一般都是由于jar包不全导致的。

问题一：抛出 NestableRuntimeException
