Hence, you can expect Java Multithreading interview questions in systems design interviews at FAANG+ companies. Get Ready For Your Up...
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...
OOPS is a programming approach which provides solution to real life problems 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,...

Inheritanceis another important concept in object-oriented programming. Inheritance is amechanism by which one class acquires the properties and behaviors of the parent class. It’s essentially creating a parent-child relationship between classes. In Java, we will use inheritance mainly for code reusab...
Encapsulation – An another OOPS concept that is used to hide the behaviour and properties of an object. This concept allows only appropriate outside access. Also, it avoids other objects to access the properties and methods of encapsulated object directly.封装—另一个 OOPS 概念，用于隐藏对象的...
