To learn more about this concept, check thefree inheritance in the Java course. Third Pillar of OOP: Polymorphism Definition: Polymorphism allows objects to take multiple forms, enabling the same method to behave differently based on context. It is achieved through: Compile-time Polymorphism (Method...
Abstraction is the concept of hiding the internal details and describing things in simple terms. For example, a method that adds two integers. The internal processing of the method is hidden from the outer world. There are many ways to achieve abstraction in object-oriented programmings, such a...
The relationship between two separate classes with the help of objects is called association. A basic concept in Java describes the connection between two or more objects. For example; let us take a connection between the airplane and the passengers. Many passengers associate with one airline, whi...
In this section, we’ll look at the top 30 interview questions on various Java OOPS concepts. Java is an Object-Oriented Programming language as it uses Objects that acquire certain properties with the help of functions and methods. Note that hiring managers askinterview questions on Java OOPSc...
with the help of algorithms based on real world. It uses real world approach to solve a problem. So object oriented technique offers better and easy way to write program then procedural programming languages such as C, ALGOL, PASCAL etc.Click here to watch video on OOPS concept in Java ...
Example of encapsulation: A class in java is a simplest example of encapsulation. It keeps the data(variables) and behavior(methods) of an entity together. A class also restricts access to these data and behavior through the use of access specifiers. The concept of keeping instance variables ...

Many known libraries such as for example Spring or Hibernate choose the latter approach which is popular among their users under the term of using Plain Old Java Objects. As a result, code generation has become an ubiquitous concept in the Java space. Byte Buddy is an attempt to innovate ...
