Lesson: Object-Oriented Programming ConceptsIf you've never used an object-oriented programming language before, you'll need to learn a few basic concepts before you can begin writing any code. This lesson will introduce you to objects, classes, inheritance, interfaces, and packages. Each ...
Object-oriented programming embodies three main characteristics.1. Encapsulation: data and operations on data encapsulated together, through abstraction, that is, from the concrete examples of common properties to form a general concept, such as the concept of class.2. inheritance: subclasses can inher...
2. Object-Oriented Programming As we mentioned, Java is an object-oriented programming language that organises and structures code based on the concept of “objects.” Objects happen to be instances of classes. Classes, on the other hand, define the blueprint or template for creating objects. ...
Object-oriented programming may be seen as a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a list of instructions to the computer. In OOP, each object is capable of receiving messages, processing data, and sending messages to other obje...
4.1. Introduction to Object-Oriented Programming Object-oriented programming, or OOP for short, is the dominant programming paradigm these days, having replaced the "structured," procedural programming techniques that were developed in the 1970s. Since Java is object-oriented, you have to be familiar...
Since you can call SayHi() without creating an object first, the this reference doesn’t exist. However, this is still not a function in the sense that say_hi() is in Python.Inheritance and Polymorphism Inheritance and polymorphism are two fundamental concepts in object-oriented programming. ...

The object-oriented programming model revolves around the concept of Objects.What is an Object?An object is an instance of a Class. It contains properties and functions. They are like real-world objects. For example, your car, house, laptop, etc. are all objects. They have some specific pr...
3.1Object Technology in Java To be truly considered "object oriented", a programming language should support at a minimum four characteristics: Encapsulation--implements information hiding and modularity (abstraction) Polymorphism--the same message sent to different objects results in behavior that's depe...
