Object Oriented Programming

Question - Feature Of Java?

Answer -

These are the features of Java, will see all of them one by one but right now we are going to understand  Object Oriented Programming Language.




*Question - What is Object Oriented Programming?

Answer - Object Oriented Programming is a paradigm ( way of writing a program ).There are many ways of programming like

1. Procedure Programming (structural programming)
2. Object-Oriented Programming *
3. Constraint Programming
4. Logical Programming
5. Functional Programming 
6.  and more ...

Note -- None of the styles is perfect. We use Object Oriented Style because of many benefits of object-oriented and it is the most popular and used.

Let's try to Define & Understanding of OOP Language  -

- It's Abbreviation of OOPs

- OOPs Stands for OBJECT ORIENTED PROGRAMMING System

- It is a kind of Model or Concept or Method of implementation of code

- Used to define implement (wright) programs

- methodology (way of developing a program) based on class and objects instead of just functions and procedures.

- In these types of programming, you have to make CLASS because without a class you can't make  OBJECTs. OOPs is based on OBJECTS that is generated from the CLASS.

- It has some important features that we will be using during developing our code. Some are
    ○ Encapsulation
    ○ Abstraction
    ○ Polymorphism
    ○ Inheritance etc (there are more features will see later)

- Examples of OOP's languages are C++, C#, JAVA, PHP, SMALL TALK  etc.

-Objects are created from Classes. (also say that object is an instance of the class)

" OBJECT-ORIENTED PROGRAMMING refers to a programming methodology based on objects, instead of just functions and procedures. These objects are organized into classes, which allow individual objects to be group together. Most modern programming languages including  C++, C#, JAVA, PHP, etc are object-oriented languages." 

0r 

" OBJECT-ORIENTED PROGRAMMING is a method of implementation in which software is organized (written) as a discrete collection of objects."

Question - What are the characteristics/features of OOP?
Answer - 

• Class
• Objects
• Inheritance 
• Abstraction 
• Encapsulation
• Polymorphism
• Modularity
• Concurrency 
• Persistence 

Note -These are the features must be satisfied for any programming language then only that language is known as object-oriented programming language.

(Don't Worry we will see all there features one by one...for now, just remember these names)
