### Use IntelliJ IDEA to run this code

#### Java is a high level, robust, object-oriented and secure programming language.

It was developed by Sun Microsystems (which is now the subsidiary of Oracle) in the year 1995.

### OOPs

OOPS is abbreviate as Object Oriented Programming system in which programs are considered as a collection of objects .Each object is an instance of a class .

1. Abstraction 

2. Encapsulation

3. Inheritence 

4. Polymorphism 

### Class 

A class is a repersentation of a type of object. It is a blueprint / templet that describe the details of an object. 

#### Object 

An object is an instance of a class. It has its own state and behavior and identity .

### Abstraction

A class which is declared with the abstract keyword is known as an abstract. 

Abstraction is a process of hiding the implementation details and showing only functionality to the user.

### Encapsulation

Encapsulation is an attribute of an object , and contain all data which is hidden . That hidden data can be restricted to the member of that class .

Levels are - Public , Protected , Private , Internal and Protected Internal 

### Inheritence

Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object.

Where one class share the structures and behavior defined another class . 

 

(a). Inheritance represents the IS-A relationship which is also known as a parent-child relationship.

(b).If a class have an entity reference, it is known as Aggregation. Aggregation represents HAS-A relationship.

### Polymorphism 

Polymorphism  is assigning behavior or value in a subclass to something that was already declear in the main class . Simply , Polymorphism takes more than one forms .

###### Method-Overloading is a class has multiple methods having same name but different in parameters.

###### Method-Overriding  If subclass (child class) has the same method as declared in the parent class
