Java programming language I have to create a remove method that removes the element at an index (ind) or space in an array and returns it. Thanks! I have to write the remove method in the code below. i attached the part where i need to write it. public class ourArrayList<T>{ private Node<T> Head = null; private Node<T> Tail = null; private int size = 0; //default constructor public ourArrayList() { Head = Tail = null; size = 0; } public int size() { return size; } public boolean isEmpty() { return (size == 0); } //implement the method add, that adds to the back of the list public void add(T e) { //HW TODO and TEST //create a node and assign e to the data of that node.
