Below programs illustrates the use of getHost() function:
Example 1:
// Java program to show the use// of the function getHost() import java.net.*; class GFG { public static void main(String args[]) { // url object URL url = null; try { // create a URL url // get the Host String Host = url.getHost(); // display the URL System.out.println("URL = " + url); // display the Host System.out.println("Host = " + Host); } // if any error occurs catch (Exception e) { // display the error System.out.println(e); } }} |
Output:
URL = https:// www.geeksforgeeks.org Host = www.geeksforgeeks.org
Example 2:
// Java program to show the// use of the function getHost() import java.net.*; class GFG { public static void main(String args[]) { // url object URL url = null; try { // create a URL url = new URL( // get the Authority String authority = url.getAuthority(); // get the Host String host = url.getHost(); // display the URL System.out.println("URL = " + url); // display the Host System.out.println("Authority = " + authority); // display the Host System.out.println("Host = " + host); } // if any error occurs catch (Exception e) { // display the error System.out.println(e); } }} |
Output:
URL = https:// www.geeksforgeeks.org:80/url-samefile-method-in-java-with-examples/ Authority = www.geeksforgeeks.org:80 Host = www.geeksforgeeks.org
Example 3: If we create a URL with no host name and ask for the host using the getHost() function the function returns blank String.
// Java program to show the// use of the function getHost() import java.net.*; class GFG { public static void main(String args[]) { // url object URL url = null; try { // create a URL // get the Host String Host = url.getHost(); // display the URL System.out.println("URL = " + url); // display the Host System.out.println("Host = " + Host); } // if any error occurs catch (Exception e) { // display the error System.out.println(e); } }} |
