The aim of inheritance is to provide the reusability of code so that a class has to write only the unique features and rest of the common properties and functionalities can be extended from another class.The class that extends the features of another class is known as child class, sub class or derived class.The class whose properties and functionalities are used(inherited) by another class is known as parent class, super class or Base class. What is inheritance in Java?The process by which one class acquires the properties(data members) and functionalities(methods) of another class is called inheritance. Enumeration variables are used and declared in much a same way as you do a primitive variable. Even though enumeration defines a class type and have constructors, you do not instantiate an enum using new. Each enumeration constant is public, static and final by default. This is the general procedure to implement abstraction in OOPS.The idea behind encapsulation is to hide the implementation details from users. We can provide access only for required functions and properties to the other programs. We can hide them from the outer world through access modifiers. An object contains some properties and methods. What is abstraction in Java?Objects are the building blocks of Object-Oriented Programming. ![]() How to initialize array in java?

What is core java?“Core Java” is Sun’s term, used to refer to Java SE, the standard edition and a set of related technologies, like the Java VM, CORBA, et cetera. The data associated with a class or object is stored in variables the behaviour associated with a class or object is implemented with methods. When you instantiate a class you create an object that looks and feels like other instances of the same class. What is a class in java?A class–the basic building block of an object-oriented language such as Java–is a template that describes the data and behaviour associated with instances of that class. How to check java version?Execute java -version on a command prompt/terminal. Methods are used to perform certain actions, and they are also known as functions. Also, note that they’re talking about a set of libraries rather than the programming language.
