The Object-Oriented Programming methodology introduces the principles of inheritance, encapsulation, abstraction, and polymorphism through the use of classes and objects. The goal of OOP is to connect data and functions in order to increase code stability and security. You must be thoroughly clear wit...
Interview questions on Java OOPS concepts are usually asked on Classes, Methods, Functions, Polymorphism, Inheritance, Constructors, Destructors, Data-Binding, Abstraction, Encapsulation, Multithreading, and Synchronization. Q2. Are interview questions on Java OOPS concepts asked at SE interviews at FAANG...
By extending the Thread class, we cannot extend any other class, as Java does not allow multiple inheritances while implementing the Runnable interface; we can also extend other base class(if required). By extending the Thread class, each of thread creates the unique object and associates with ...
Yes, since inheritance inherits everything from the super class and interface, it may make the subclass too clustering and sometimes error-prone when dynamic overriding or dynamic overloading in some situation.104. When is the ArrayStoreException thrown?When copying elements between different arrays, ...
Run-time polymorphismuses inheritance and interface. What does an interface in Java refer to? An interface as it relates to Java is a blueprint of a class or a collection of abstract methods and static constants. Each method is public and abstract, but it does not contain any constructor. ...

Inheritance is a fundamental concept in object-oriented programming, where a class inherits properties and behaviors from another class, known as the superclass or base class. The class that inherits these properties is called the subclass or derived...
Another few indicators to look out for, which are a sign that the interview candidate is a step ahead of the compiler:Do they use inheritance correctly – in particular, do they enforce that T extends Comparable<T>? Do they add @Override annotations?
1. Questions on OOP Core Concepts 1.1. What are the four major pillars of OOP? The major pillars on which OOP relies areEncapsulation,Inheritance,Polymorphism, and Abstraction. Encapsulationprovides security to our application; it consists ofprivatevariable declarations (data hiding) and accessor metho...
OOP is a programming paradigmthat assumes centrality in Java because it allows for codes that are modular, reusable, maintainable, or easy to develop. The most characteristic features that it uses include classes and objects, encapsulation, inheritance, polymorphism, and abstraction. ...
