Clock

Instructions

Implement a clock that handles times without dates.

You should be able to add and subtract minutes to it.

Two clocks that represent the same time should be equal to each other.

In order to satisfy the requirement that two clocks are considered equal just when they are set to the same time, you will need to override the equals and hashcode methods in your Clock class.

For more information on how to override these methods, see this JavaWorld article.
