緯度を正確なアドレスに変換

くだらない話は多く言わないで、みんなは直接コードを見て、コードは私がダウンロードした後に修正テストを経たのです

package a;

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

public class Demo0 {
	public static String GetAddr(String longitude, String latitude) {//  
		String addr = "";
		String url = String.format(
				"http://ditu.google.cn/maps/geo?output=csv&key=abcdef&q=%s,%s",
				latitude, longitude);
		URL myURL = null;
		URLConnection httpsConn = null;
		try {
			myURL = new URL(url);
			httpsConn = (URLConnection) myURL.openConnection();
			if (httpsConn != null) {
				InputStreamReader insr = new InputStreamReader(
						httpsConn.getInputStream(), "UTF-8");
				BufferedReader br = new BufferedReader(insr);
				String data = null;
				if ((data = br.readLine()) != null) {
					System.out.println(data);
					String[] retList = data.split(",");
					if (retList.length > 2 && ("200".equals(retList[0]))) {
						addr = retList[2];
						addr = addr.replace("", "");
					} else {
						addr = "";
					}
				}
				insr.close();
			}
		} catch (IOException e) {
			e.printStackTrace();
			return null;
		}
		return addr;
	}

	public static void main(String[] args) {
		String addr = GetAddr("116.38689", "39.90578");
		System.out.println(addr);
	}
}
