Example 1

The following example shows the usage of Java URLConnection getDate() method for a valid url with https protocol. In this example, we're creating an instance of URL class. Using url.openConnection() method, we're getting the URLConnection instance. Using getDate(), we're getting the value of date header field of URLConnection instance and printing the same −

package com.tutorialspoint;

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.time.Instant;
import java.util.Date;

public class UrlConnectionDemo {
   public static void main(String [] args) {
      try {
         URL url = new URL("https://www.tutorialspoint.com");
         URLConnection urlConnection = url.openConnection();

         System.out.println(Date.from(Instant.ofEpochMilli(urlConnection.getDate())));

      } catch (IOException e) {
         e.printStackTrace();
      }
   }
}

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