The following example shows the usage of Java URL getQuery() method for a valid url with https protocol without query part. In this example, we're creating an instance of URL class. Now using getQuery() method, we're getting the query and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;

public class UrlDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("https","www.tutorialspoint.com","/index.htm");
