What is OOP and which concepts are a core part of OOP ?
posted 3 years ago
I am not sure I know what is the essence of OOP and what is not. Is it essentially just this - being able to represent everything as fields and methods, ie encapsulation ? http://en.wikipedia.org/wiki/Object-oriented_programming Wikipedia says that OOP is also about polymorphism, Inheritance etc. But, are those things the essence of OOP or peripheral features ?

I am a "newbie" too. Please verify my answers before you accept them.
The essence is really that you model concepts with objects. Whether specific features such as classes, inheritance and polymorphism are "fundamental" or "peripheral" features is really a theoretical discussion and for many features there isn't even a clearly correct answer, it depends on opinion.
