public class Main {
public static void main(String[] args) throws Exception {
int size;
URL url = new URL("http://www.example.com/wp-content/themes/example/assets/img/newlogo.png");
URLConnection conn = url.openConnection();
size = conn.getContentLength();
if (size < 0)
System.out.println("Unable to get file size.");
