In java:

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 ... }
