public class StringHashedSet<E>
extends ArraySet<E>

A set where the elements are uniquely referenced by their string representation as given by the objects toString() method. No 2 objects with the same toString() can be in the set.

The contains(Object elem) and get(Object elem) methods can be called with Strings as elem parameter. For get(Object elem), the object that has been added is returned, and not its String representation.

Though it's possible to store Strings as objects in this class, it doesn't make sense as you could use ArraySet for that equally well.

You shouldn't use the ArrayList specific functions like those that take index parameters.

It is not possible to add null elements.
