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(                    "https:// www.geeksforgeeks.org:80/url-samefile-method-in-java-with-examples/");              // 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);        }    }} |
Output:
URL = https: Host =
