Advice:
- Learn SOLID principles and try to use it.
- Think about class as physical object: what can it do, who can change its data, what it should not do.
- Think, how objects can communicate with each other.
- Base the relationships on abstraction.
- Make hermetic objects.
- Classes and methods should not do too much.
- A class should change only itself data.
- Find common responsibilities and put in special classes (like validating mail address).
- Write clean, readable and pretty code.
- Chose composition over inheritance.
How to better program in object-oriented paradigm:
Read a book: The Object-Oriented Thought Process — Matt Weiffeld and make exercises.
How to exercise:
Find an application, which is written in structural paradigm and change it into object-oriented.
