The following example shows the usage of Java URL getRef() method for a valid url with https protocol without ref part. In this example, we're creating an instance of URL class. Now using getRef() method, we're getting the ref 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");
         String result = url.getRef();
         System.out.println(result);
      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

Let us compile and run the above program, this will produce the following result −

Output
