Important points to tackle a OOP problem.
1. Write or draw about the problem.
2. Extract key components from 1 and research them.
3. Create a class hierarchy and object map for the concepts.
4. Code the classes and a test to run them.
5. Repeat and refine.
Make a list of nouns and verbs and see how they are related.
Nouns can be classes and verbs can be functions.
Build a complete class hierarchy or a simple tree.
Write test code, real code, test code and repeat till all your tests succeeded.
