            // 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.

    }
}

Output:

URL = https:// www.geeksforgeeks.org:80/url-samefile-method-in-java-with-examples/
