基于JAVA的成语词典接口调用代码实例.doc

1、基于 JAVA的成语词典接口调用代码实例接口描述：基于 JAVA的成语词典接口调用代码实例接口平台：聚合数据import java.io.BufferedReader;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.UnsupportedEncodingException;import .HttpURLConnection;import .URL;import .URLEnco
