abstract isa non-access modifier in java applicable for classes, methods but not variables. It is used to achieve abstraction which is one of the pillar of Object Oriented Programming(OOP). Following are different contexts where abstract can be used in Java. What is use of abstract class? The...
Encapsulation:Abstract classes can encapsulate common attributes and behaviors, hiding the complexities from the user. This abstraction allows developers to change internal workings without affecting classes that inherit from the abstract class. Hierarchical Inheritance:Abstract classes lay the foundation for ...
When the object data is not visible to the outer world, it creates data abstraction. If needed, access to the Objects’ data is provided through some methods. Abstraction in Java is implemented throughinterfacesandabstract classes. They are used to create a base implementation or contract for th...

Object-based languages support the full complement of features of object-oriented programming. These features are as follows: Abstraction.This feature refers to hiding implementation code that is not necessary for use by other objects. In other words, objects only reveal those operations that are rel...

In programming, instantiation is the creation of a realinstanceor particular realization of an abstraction ortemplate, such as aclassofobjectsor a computerprocess. To instantiate is to create such an instance by, for example, defining one particular variation of an object within a class, giving ...
