Answers Code

The getRef method of the URL class can be used to get the reference or anchor/reference part of the specified URL.

Syntax

public String getRef()

The getRef method doesn’t take any arguments. The return type of this method is String. If the URL doesn’t have an anchor, then getRef returns null.

The URL class is present in the java.net package.

Parts of the url

The image above illustrates the parts of the URL.

Code

The code below demonstrates how to use the getRef method.

import java.net.URL;
class GetRefExample {
public static void main( String args[] ) {
try {
URL url= new URL("https:// www.educative.io#test");
//Get Reference or anchor
String reference=url.getRef();
System.out.println("The URL is : "+url);
System.out.println("Reference or anchor is : "+reference);
} catch (Exception e) {
System.out.println(e);
}
}
}

Explanation

In the code above:

  • In line 6, we create a URL object.
URL url= new URL("https:// www.educative.io#test");
  • In line 8, we use the getRef method to get the reference of the URL object.
String reference=url.getRef();
  • In lines 9-10, we print the URL and the reference of the URL.
