What is Abstraction in OOP?Abstraction is selecting data from a larger pool to showonly the relevant details to the object. It helps to reduceprogramming complexity and effort. In Java, abstraction isaccomplished using Abstract classes and interfaces. It is one ofthe most important concepts of OOPs..
Moreover, what is abstraction in OOP with example?
Abstraction means displaying only essentialinformation and hiding the details. Data abstraction refersto providing only essential information about the data to theoutside world, hiding the background details or implementation.Consider a real life example of a man driving acar.

Abstraction shows the relevant information andrejects the non-essential details. On the other hand, datahiding is used to hide the data from the parts ofthe program. Abstraction is used in class to create a newuser-defined datatype. As against, in classes data hiding isused to make the data private.WHAT IS interface in OOP?

OOP concepts in Java are the main ideas behindJava's Object Oriented Programming. They are an abstraction,encapsulation, inheritance, and polymorphism. Basically, JavaOOP concepts let us create working methods and variables,then re-use all or part of them without compromisingsecurity.What is an abstraction in writing?
Abstraction. Abstraction in its main senseis a conceptual process where general rules and concepts arederived from the usage and classification of specific examples,literal ("real" or "concrete") signifiers, first principles, orother methods.Why do we need abstract class?
Java Abstract class can implement interfaceswithout even providing the implementation of interface methods.Java Abstract class is used to provide common methodimplementation to all the subclasses or to provide defaultimplementation. We can run abstract class in javalike any other class if it has main() method.How do you achieve abstraction?
Abstraction is process of hiding theimplementation details and showing only the functionality.Abstraction in java is achieved by using interfaceand abstract class.

Encapsulation is one of the fundamental conceptsin object-oriented programming (OOP). It describesthe idea of bundling data and methods that work on that data withinone unit, e.g., a class in Java. This concept is also often used tohide the internal representation, or state, of an object from theoutside.What is data encapsulation in OOPs?
Encapsulation is a process of combiningdata members and functions in a single unit called class.This is to prevent the access to the data directly, theaccess to them is provided through the functions of the class. Itis one of the popular feature of Object OrientedProgramming(OOPs) that helps in datahiding.What is Polymorphism in Java?
