Java Practice It | Exercise 16.15: equals | LinkedList, #implementing instance methods

Problem:

Question:
Write a method equals2 that accepts a second list as a parameter and that returns true if the two lists are equal and that returns false otherwise. Two lists are considered equal if they store exactly the same values in exactly the same order and have exactly the same length. (Note: On the original section handout, this method is called equals; but Practice-It already defines an equals method for LinkedIntList for internal use, so we must call your method equals2 here to avoid a conflict.)

Assume that you are adding this method to the LinkedIntList class as defined below:

public class LinkedIntList {
private ListNode front; // null for an empty list
...
}
