Explain the concepts of OOPS and provide real-life examples.

Question

Accepted Answer

OOP concepts in Java include encapsulation, inheritance, polymorphism, and abstraction, essential for building scalable applications.

Encapsulation: Bundling data and methods. Example: A class 'Car' with private attributes like 'speed' and public methods to access them.
Inheritance: Deriving new classes from existing ones. Example: 'ElectricCar' inherits from 'Car', adding features like battery capacity.
Polymorphism: Ability to take many forms. Example: Method overriding where a subclass provides a specific implementation of a method.
Abstraction: Hiding complex implementation details. Example: An interface 'Vehicle' that defines methods like 'start()' without implementation.

Java is a pure object oriented programming language. Object - is real word entity such as table, pen, car etc. Object has 3 characteristics State, Behavior's, Identity. Class- A class is a group of objects which has common properties It is a template or blueprint from which object are created. In Inheritance in java is a mechanism of in which in one object acquired all the properties and behavior's of a parent object. Inheritance is a represent the IS-A Relationship which is known as parent-child relationship.  Polymorphism- we can perform single action in a different ways. It has 2 types - compile time polymorphism and run time polymorphism. Abstraction- is a process of hiding the information and showing the functionality to the user. A class is declared as abstract is known as abstract class. It can have abstract and non abstract methods. It needs to be extend and its method implemented. Encapsulation in java is the process of wrapping the code and data together to the single unit. It provides only getter and setter methods. It is the way of data hiding.
