Read what your current textbook tells you. Try to understand it. Then come back with specific questions.
Here is a basic idea to start with. An object exists and it does something. You have no idea how
it does what it does. All you know is what
it does. What information it needs from you and what information it will give to you. All else is hidden

That is a starting point.
