What are the main OOPS concepts in java and explain one by one?

Question

Accepted Answer

Java OOPS concepts include inheritance, polymorphism, encapsulation, and abstraction.

Inheritance allows a class to inherit properties and methods from another class.
Polymorphism allows objects to take on multiple forms and behave differently based on their context.
Encapsulation hides the implementation details of a class and only exposes necessary information.
Abstraction allows for the creation of abstract classes and interfaces that can be implemented by other classes.
Example: A Car class can inherit properties and methods from a Vehicle class using inheritance.
Example: Polymorphism can be seen in a Shape class that can take on different forms such as Circle or Square.
Example: Encapsulation can be used to hide the implementation details of a BankAccount class.
Example: Abstraction can be seen in an abstract class Animal that can be implemented by specific animal classes like Dog or Cat.

Accepted Answer

It is a object oriented Programming Language which is design around objects, or data, instead of functions
 1) Class- definition of the methods and variables in a particular kind of object.
2) Method-method is a procedure which is associate with the class
3) Encapsulation-bundling of data and methods operating on this data into one unit.

Accepted Answer

The main principles of OOPs in Java are encapsulation, inheritance, polymorphism, and abstraction. Encapsulation ensures that the internal state of an object is hidden and can only be accessed through public methods. Inheritance allows one class to inherit properties and behavior from another

Accepted Answer

Polymorphism
Inheritance
Abstraction
Encapsulation
Polymorphism,which means the object can have may forms,we can achieve polymorphism by using methodoverloading and methodoverriding
Inheritance,class is inherited by another class or class is derived from another class,subclass ,super classes
Abstraction,hiding the internal application to the external world and highliting the services,Data hiding is happen in abstraction,by using private keyword.
Encapsulation,combination of datahiding and methods.which can have variables and multiple methods
