equals

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 our site 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
    ...
}
Partial class: Write code that will become part of an existing class as described. You do not need to write the complete class, just the portion described in the exercise.
