Let’s look into these object-oriented programming concepts one by one. We will use Java programming language for code examples so that you know how to implement OOPS concepts in Java. 1. Abstraction Abstraction is the concept of hiding the internal details and describing things in simple terms...
OOPs Concept in Java with Examples Java, renowned for its simplicity, reliability, and portability, has been a cornerstone in the programming landscape for decades, largely due to its effective use of OOP (Object-Oriented Programming) concepts. The inception of Java, with its oops concepts in j...
In Java everything isencapsulated under classes. Class is the core of Java language. It can be defined asa template 封装在class下。 类是Java语言的核心。 可以将其定义为描述特定实体的行为和状态的模板 A class defines new data type. Once defined this new type can be used to create object of ...
Ans: Inheritance is one of main pillars of OOPs concept. Some objects share certain properties and behaviors. By using inheritance, a child class acquires all properties and behaviors of parent class. There are the following reasons to use inheritance in java. We can reuse...

Encapsulation is an OOPS concept to create and define the permissions and restrictions of an object and its member variables and methods. A very simple example to explain the concept is to make the member variables of a class private and providing public getter and setter methods. Java provides...
An object-oriented paradigm is to design the program using classes and objects. The object is related to real-word entities such as book, house, pencil, etc. The oops concept focuses on writing the reusable code. It is a widespread technique to solve the problem by creating objects. ...

In the above program, it is not clear whether class A’s variable has been called or class B’s variable a has been called. In that case, JVM will throw an error. To solve this problem, concept of Interface was introduced. In Java, multiple interface is allowed but multiple inheritance...
