Hi Guy’s
So this blog is all regarding the OOPS concepts. Let’s start from the very basic concept of Object and Class.

- Introduction
- Inheritance
- Polymorphism
- Encapsulation
What is an Object?
An object is a software collection of related state and performance.
Software objects are regularly used to model the real-world objects that you find in daily life. Real-world substance share two individuality: They all have state and behavior.
Some examples of real world object can be : Bike , Chair , Dogs, have state (name, color, breed, hungry) and behavior (barking, fetching, wagging tail).
Software objects are theoretically comparable to real-world objects:
They too consist of state and connected behavior.An object stores its state in fields (variables in some programming languages) and exposes its performance through methods (functions in a few programming languages).
Methods function on an object’s inside state and serve as the primary device for object-to-object message.
Defeat inside state and requiring all communication to be performed through an object’s methods is known as ( data encapsulation — a fundamental principle of OOP )
What Is a Class?
A class is a blueprint or example from which objects are produced.
What Is Inheritance?
Inheritance provides a great and natural device for organizing and structuring your software.
How to achieve Inheritance in Java ?
extends keyword is used to inherit features of a class.
What Is an Interface?
An interface is a deal between a class and the external world.
When a class tools an interface, it promises to provide the behavior published by that interface.
What Is a Package?
A package is a namespace for organizing classes and interfaces in a logical manner.
Placing your code into packages makes large software projects easier to manage.
