Simple Reverse Geo-coding in Java using Google Map

The Java Class

package geo;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class MyGeo {
public static void main(String ar[]) throws Exception {
System.out.println(new MyGeo().getAddress("13.031067,80.239656"));
public String getAddress(String latlong){
String address = null;
String gURL = "" + latlong + "&sensor=true";
try {
DocumentBuilderFactory df = DocumentBuilderFactory.newInstance();
DocumentBuilder db = df.newDocumentBuilder();
Document dom = db.parse(gURL);
Element docEl = dom.getDocumentElement();
NodeList nl = docEl.getElementsByTagName("result");
if (nl != null && nl.getLength() > 0){
for(int i=0;i<nl.getLength();i++){
String temp=((Element)nl.item(i)).getElementsByTagName("formatted_address").item(0).getTextContent();
} catch (Exception ex) {
address = "Err";
return address;
public String getAddress(String lat, String lon) {
return getAddress(lat+ "," + lon);
public String getAddress(double lat, double lon) {
return getAddress("" + lat, "" + lon);
