    try {
    URL oracle = new URL("http://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+Vi ew,+CA&sensor=true");
    BufferedReader in = new BufferedReader(
    new InputStreamReader(oracle.openStream()));
    StringBuilder responseBuilder= new StringBuilder();

    String inputLine;
    while ((inputLine = in.readLine()) != null)
    {
    responseBuilder.append(inputLine + '\n');
    }
    NEWFIELD= inputLine;
    generateRow();
    in.close();

    }catch (Exception ex){
    ex.printStackTrace();
    }



    I went through some material and was able to develop above code.
    with this code i am able to read the last line of Google api xml output.


    Can anyone guide me providing suggestion to on to read the entire xml (from http://maps.googleapis.com/maps/api/...CA&sensor=true) and same it in NEWFIELD??

    The code saves all of the response it receives in the responseBuilder StringBuilder object. You need to extract it from there into a String.
