OO programming characters

From wiki:

 

some basic characters:

 

encapsulation, modularity,polymorphism, and inheritance

 

 

Some basic concepts:

 

Class,  defines the abstract characteristics of an object(thing)

 

Object, a pattern (exampler) of a class

 

Intance, the instance is the actual object created at the runtime

 

Method, an object's abilities

 

Abstraction, it is simplifing complex reality by modelling class appropriate the problem

 

Encapsulation, conseals the functional details of a class from object that send message to it

 

Polymorphism, allow the programmer to treat derived class members  just like their parents members

 

Decoupling, allows for the separation of object interactions from classes and inheritance into distinct layers of abstraction
