Function Signature
public String getAuthority()

url.getAuthority()
Parameter This function does not require any parameter
Return Type The function returns String Type which is the authority of the specified URL.
Below programs illustrates the use of getRawAuthority() function:
Example 1:
// Java program to show the// use of the function getAuthority()  import java.net.*;  class GFG {    public static void main(String args[])    {        // URI  object        URI uri = null;          try {            // create a URI            uri                = new URI(                    "https://www.geeksforgeeks.org");              // get the Authority            String authority                = uri.getAuthority();              // display the URI            System.out.println("URI = " + uri);              // display the Authority            System.out.println("Authority = "                               + authority);        }          // if any error occurs        catch (Exception e) {              // display the error            System.out.println(e);        }    }}
URI = 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 GFG {    public static void main(String args[])    {        // url  object        URI uri = null;          try {            // create a URI            uri                = new URI(                    "https://www.geeksforgeeks.org:80");              // get the Authority            String authority                = uri.getAuthority();              // get the Host            String host = uri.getHost();              // display the URI            System.out.println("URI = " + uri);              // 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);        }    }}
URI = https://www.geeksforgeeks.org:80
Authority = www.geeksforgeeks.org:80
Host = www.geeksforgeeks.org

Example 3: The value returned by getAuthority() and getRawAuthority() is same except that all sequences of escaped octets are decoded. The getRawAuthority() returns the exact value of the string as provided by the user but the getAuthority() function decodes the sequence of escaped octets if any.
// Java program to show the// use of the function getAuthority()  import java.net.*;  class GFG {    public static void main(String args[])    {        // url  object        URI uri = null;          try {            // create a URI            uri                = new URI(                    "https://www.geeksforgeeks%E2%82%AC.org:80");              // get the Authority            String authority                = uri.getAuthority();              // get the Raw Authority            String Raw_authority                = uri.getRawAuthority();              // display the URI            System.out.println("URI = " + uri);              // display the Authority            System.out.println("Authority = "                               + authority);              // display the Raw Authority            System.out.println("Raw Authority = "                               + Raw_authority);        }          // if any error occurs        catch (Exception e) {              // display the error            System.out.println(e);        }    }}
URI = https://www.geeksforgeeks%E2%82%AC.org:80
Authority = www.geeksforgeeks?.org:80
Raw Authority = www.geeksforgeeks%E2%82%AC.org:80
