In the above examples, java compiler doesn’t know the actual implementation class of Shape that will be used at runtime, hence runtime polymorphism. 4. Inheritance Inheritanceis the object-oriented programming
OOPs (Object-Oriented Programming System) is a programming concept, methodology, or paradigm, that is a core of Java programming used to design programming using classes and objects. The OOPs concepts in Java build on the four main principles. - Encapsulation: Binds data and operations that work...
Multithreading is an important concept that helps to solve present-day coding and design problems. Hence, you can expect Java Multithreading interview questions in systems design interviews at FAANG+ companies.

While learning Object-Oriented Programming (oops concepts), I decided to dive into its history to fully know what is oops concept and it turned out to be fascinating. The term “Object-Oriented Programming” (OOP), also known as OOPs principles in python, was coined by Alan Kay around 1966...
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 ...
In this article, we will explore the concept of running Apache NiFi in a Docker container and understand the significance of the message, “The process is running with CompressedOops enabled, and the Java”. We will provide step-by-step instructions on how to run NiFi in a Docker container...
A class is typically a universal concept. For example, if you have objects that are mammals, amphibians and invertebrates, the class could be Animals. Object-Oriented Programming (OOP) students also learn Java C# (programming language) Programming Fundamentals Unity C++ (programming language) Design...
Can you explain the concept of ‘Composition over Inheritance’? This principle suggests using composition (including objects of other classes as members) over inheritance (extending classes) for code reuse, to avoid the complications of deep inheritance hierarchies. What are Magic Methods in OOP? Ma...
