The getRef() function is a part of URL class. The function getRef() returns the Reference or anchor part of a specified URL.

Function Signature:

public String getRef()

Syntax:

url.getRef()

Parameter: This function does not require any parameter

Return Type: The function returns String Type

Below programs illustrates the use of getRef() function:

Example 1: Given a URL we will get the Reference or anchor using the getRef() function.




// Java program to show the
// use of the function getRef()
  
import java.net.*;
  
class Solution {
    public static void main(String args[])
    {
        // url  object
        URL url = null;
  
        try {
  
            // create a URL
            url= new URL("https:// www.geeksforgeeks.org#Arnab_Kundu");
  
            // get the  Reference or anchor
            String _Ref=url.getRef();
               
            // display the URL
            System.out.println("URL = "+url);
               
            // display the  Reference or anchor
            System.out.println(" Reference or anchor="+_Ref);
        }
  
        // if any error occurs
        catch (Exception e) {
  
            // display the error
            System.out.println(e);
        }
    }
}

Output:

URL = https:// www.geeksforgeeks.org#Arnab_Kundu
 Reference or anchor=Arnab_Kundu

Example 2: Now we will not provide any anchor and use the function to get the Reference or anchor and see the results.




// Java program to show the
// use of the function getRef()
  
import java.net.*;
  
class Solution {
    public static void main(String args[])
    {
        // url  object
        URL url = null;
  
        try {
  
            // create a URL
            url = new URL("https:// www.geeksforgeeks.org");
  
            // get the  Reference or anchor
            String _Ref = url.getRef();
  
            // display the URL
            System.out.println("URL = " + url);
  
            // display the  Reference or anchor
            System.out.println(" Reference or anchor= "
                               + _Ref);
        }
  
        // if any error occurs
        catch (Exception e) {
  
            // display the error
            System.out.println(e);
        }
    }
}

Output:

URL = https:// www.geeksforgeeks.org
 Reference or anchor= null
