Author: Whitaker Brand

Write a method toString2 that returns a string representation of the list, such as "[5, -2, 9]". (Note: On the original section handout, this method is called toString; but Practice-It already defines a toString method for LinkedIntList for use in other problems, so we must call your method toString2 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
    ...
}
Type your solution here:


This is a partial class problem. Submit code that will become part of an existing Java class as described. You do not need to write the complete class, just the portion described in the problem.
