CS $1332$ JAVA HW $2$ CIRCULAR SINGLY LINKED LIST. PLEASE HELP!!!!! CORRECT ANSWER GETS A THUMBS UP AND GRATITUDE!$----------------------------------------------------------------------$Circular Singly$-$Linked ListYou are to code a circular singly$-$linked list with a head reference. A linked list is a collection of nodes, each having a data item and a reference pointing to the next node. Since it must be circular, the next reference for the last node in this list will point to the head node. Do not use a phantom node to represent the start or end of your list. A phantom or sentinel node is a node that does not store data held by the list and is used solely to indicate the start or end of a linked list. If your list contains n elements, then it should contain exactly n nodes.Your linked list implementation will implement the LinkedListInterface provided. It will use the default constructor $($the one with no parameter$)$ which is automatically provided by Java. Do not write your own constructor.NodesThe linked list consists of nodes. A class LinkedListNode is provided to you. LinkedListNode has setter and getter methods to access and mutate the structure of the nodes.AddingYou will implement three add$()$ methods. One will add to the front, one will add to the back, and one will add anywhere in the list. See the interface for more details.RemovingRemoving, just
