How to explain an object?

Question

It\'s been years since I thought of this, but I am training some real juniors soon and need to explain what an object is to someone who doesn\'t know what it is.

B

Answer 1

I would go by Grady Booch definition: An Object is one which has a State, Behaviour and Identity. Member variables contribute to State; Methods contribute to Behaviour and some unique attributes contribute to identity. For eg., email could be an identity attribute for a Person Object.
