Concepts of OOPs

•        Object

•        Class

•        Data abstraction

•        Data encapsulation

•        Modularity

•        Inheritance

•        Polymorphism

Class

•        A class is a group of objects that share common properties and relationships.

Object

•        An object is an identifiable entity with some characteristics and behavior.

Data Abstraction

•        Abstraction refers to the act of representing essential features without including the background details or explanations.

Data Encapsulation

•        The wrapping up of data and operations / functions (that operate on the data) into a single unit (called class) is known as encapsulation.

Modularity

•        Modularity is the property of a system that has been decomposed into a set of cohesive and loosely coupled modules.

Inheritance

•        Inheritance is the capability of one class of things to derive capabilities or properties from another class.

Polymorphism

•        Polymorphism is the ability for a message or data to be processed in more than one form.

Advantages of OOP

•        Re-use of code

•        Ease of comprehension

•        Ease of fabrication and maintenance

•        Easy redesign and extension

Disadvantage of OOP

•        With OOP, classes tend to be overly generalised.

•        The relations among classes become artificial at times.

•        The OOP programs’ design is tricky.

•        Proper Planning & Design is required

•        Programmer need proper skills for development
