Consider the following code for a LinkedList: $($CLO$-2,$ CLO$-3,$ CLO$-4,$ CLO$-5)$public class LinkedList $($protected Node head $=$ null;public void add $($int data$)///$ Code toalways add the node at the head of the listclass Node l int data;Node next $=$ null;public Node $($int data$)$this$.$data $=$ data;Below write a class Sortedlinked ist that extends the class above and overrides the add method so when new data is added to the Sorted Linked List the nodes are always added in sorted order. You may write code you would add to the Node class provided above, just be sure to note which code would be in the Node class. You may not assume any other methods are present in these classes.
