Last Updated :
02 Jan, 2019
The getAuthority() function is a part of URI class. The function getAuthority() returns the authority of a specified URI. The Authority part of the URL is the host name and the port of the URI.
Function Signature
public String getAuthority()
Syntax:
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:
import java.net.*;
class GFG {
public static void main(String args[])
{
URI uri = null ;
try {
uri
= new URI(
String authority
= uri.getAuthority();
System.out.println( "URI = " + uri);
System.out.println( "Authority = "
+ authority);
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
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.
import java.net.*;
class GFG {
public static void main(String args[])
{
URI uri = null ;
try {
uri
= new URI(
String authority
= uri.getAuthority();
String host = uri.getHost();
System.out.println( "URI = " + uri);
System.out.println( "Authority = "
+ authority);
System.out.println( "Host = " + host);
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
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.
import java.net.*;
class GFG {
public static void main(String args[])
{
URI uri = null ;
try {
uri
= new URI(
String authority
= uri.getAuthority();
String Raw_authority
= uri.getRawAuthority();
System.out.println( "URI = " + uri);
System.out.println( "Authority = "
+ authority);
System.out.println( "Raw Authority = "
+ Raw_authority);
}
catch (Exception e) {
System.out.println(e);
}
}
}
|
Output:
URI = https://www.geeksforgeeks%E2%82%AC.org:80
Authority = www.geeksforgeeks?.org:80
Raw Authority = www.geeksforgeeks%E2%82%AC.org:80
