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
// 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
// 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
