Below programs illustrates the use of getHost() function:
Example 1:
// Java program to show the // use of the function getAuthority() import java.net.*;
class Solution {
public static void main(String args[])
{
// url object
URL url = null ;
try {
// create a URL
url
// get the Authority
String authority
= url.getAuthority();
// display the URL
System.out.println( "URL = "
+ url);
// display the Authority
System.out.println( "Authority = "
+ authority);
}
// if any error occurs
catch (Exception e) {
// display the error
System.out.println(e);
}
}
} |
Output:
URL = https:// www.geeksforgeeks.org Authority = www.geeksforgeeks.org
Example 2: The difference between getAuthority() and getHost() function is that getAuthority() returns the host along with the port but getHost() returns only the host name.
// Java program to show the // use of the function getAuthority() import java.net.*;
class Solution {
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 Authority
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
