i dont think it is really all that different. just think of the difference
between comparing by ref and by val, and using .equals() makes perfect
sense. when you use the == operator you are asking whether the objects
refer to the same place in memory, whereas with .equals() you are asking
whether their values are equivalent. thats a powerful piece of
flexibility--one that you have elsewhere as well..
