Consider a version of the LinkedList class of Section 16.1.8 in which the addFirst method has been replaced with the following faulty version:

Develop a program ListTest with a test case that shows the error. That is, the program should print a failure message with this implementation but not with the correct implementation.

public void addFirst(Object element) { } Node newNode= new Node (); first = newNode; newNode.data newNode.next = element; = first;
