根据当前在servlet中的位置获取附近的经度和纬度

Question

其实我从android设备获取当前经纬度的值。所以根据当前位置我必须发送附近的经纬度。请给我一些建议，以便我可以在我的项目中使用它。

您可以通过输入ZIP/Postal代码得到附近Longitude & Latitude：

public static void main(String[] args) throws Exception 
    { 
    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); 
    System.out.println("Please enter a postcode:"); 
    String postcode=reader.readLine(); 
    StringBuffer input=new StringBuffer(); 
    String data=null; 
    String latLong=null; 
    String link="http://maps.google.com/maps?q="+URLEncoder.encode(postcode, "UTF-8"); 
    URL url=new URL(link); 
    HttpURLConnection connection=(HttpURLConnection)url.openConnection(); 
    BufferedReader br=new BufferedReader(new InputStreamReader(connection.getInputStream())); 
    if(connection.getResponseCode()==200) 
    { 
     System.out.println("Success"); 
     while((data=br.readLine())!=null) 
     input.append(data); 
    } 
    int x=input.indexOf("lat:"); 
    int y=input.indexOf("}",x); 
    latLong=input.substring(x,y); 
    latLong=latLong.replaceAll("lat:",""); 
    latLong=latLong.replaceAll("lng:",""); 
    System.out.println(latLong); 
    String[] array=latLong.split(","); 
    System.out.println("Latitude: "+array[0]+" and Longitude: "+array[1]+" for "+an>+postcode); 
    }
