Java Example - Obtain date information from URL response header

The following example demonstrates how to use the httpCon.getDate() method of HttpURLConnection to obtain the date information of the URL response header:

/*
 author by w3cschool.cc
 Main.java
 */import java.net.HttpURLConnection;import java.net.URL;import java.util.Date;public class Main{
   public static void main(String args[]) 
   throws Exception {
      URL url = new URL("http://www.w3cschool.cc");
      HttpURLConnection httpCon = 
      (HttpURLConnection) url.openConnection();
      long date = httpCon.getDate();
      if (date == 0)
      System.out.println("无法获取信息。");
      else
      System.out.println("Date: " + new Date(date));
   }}

The output result of the above code is:

Date: Mon May 04 11:57:06 CST 2015

The above is the Java example - getting the date information of the URL response header. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
