Java OOP – Object Oriented Programming
In Java, records are a special kind of class introduced in Java 14 as a preview feature and made stable in Java 16. Records provide a quick way of creating data-carrying classes without having to write boilerplate code. They are particularly useful in applications where you need to create classes that serve primarily as data …
Inheritance in Java allows classes to inherit properties and methods from other classes, promoting code reusability and establishing a hierarchical relationship between classes. This principle of Object-Oriented Programming (OOP) lets a subclass utilize fields and methods of its superclass, except for constructors, which are not inherited. Understanding Inheritance Superclass (Parent Class): The class whose features …
Polymorphism is a core concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. It’s one of the four major OOP principles, alongside encapsulation, inheritance, and abstraction. Polymorphism in Java enables a single interface to be used for a general class of actions. The specific …
In Object-Oriented Programming (OOP) with Java, constructors play a crucial role in initializing new objects. A constructor in Java is a special type of method that is called automatically when an instance of a class is created. Its primary purpose is to initialize the newly created object. Key Characteristics of Constructors: Name: A constructor must …
Encapsulation is a fundamental concept in Object-Oriented Programming (OOP) that involves bundling the data (attributes) and methods that operate on the data into a single unit, or class, and restricting access to some of the object’s components. This is typically achieved through the use of private variables, which are only accessible within the same class, …
Object-Oriented Programming (OOP) is a programming paradigm centered around the concept of objects, which can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). OOP is essential for several reasons: It helps organize complex code through the use of classes …
