Let the variable list be a reference variable to the head of a linked list of nodes, called LinkedNode; where LinkedNode is defined as follows: class LinkedNode { int data; LinkedNode next; LinkedNode(int i) { } data = i; next = null; A node called temp must be inserted at the front of the list, where temp is defined as: LinkedNode temp = new LinkedNode (200); Define a method called addFirst, that accepts an integer that is used as the data for a new node, and adds this new node to the beginning of the list. You may assume there is an original reference that points to the beginning of the list.
