Abstractionis very easy to understand when we relate it to a real-time example. For example, when we drive our car, we do not have to be concerned with the exact internal working of the car. We are concerned with interacting with the car via its interfaces like the steering wheel, brake...
There are constant things in life. When we refer to these, the time is irrelevant; they always mean the same thing. For example, when we say Earth, it always means the same planet. Of course, someday, the Sun will expand, explode, and destroy the Earth, but there won’t be another...
Learn the difference between association, aggregation and composition in Java with source code, examples and real-life usecases. Java OOP Concepts with Examples In this Java OOPs concepts tutorial, we will learn four major object oriented principles– abstraction, encapsulation, inheritance, and polymor...
public class PolymorphismExample { public static void main(String[] args) { Car car = new Car(); Car f = new Ford(); Car h = new Honda(); car.move(); f.move(); h.move(); } }多态性示例输出:好的。 在多态性示例类主方法中,我创建了三个对象——Car、Ford和Honda。这三个对象都...
Analysing Real-life Objects First of all, what do we expect from real-life objects isbehaviour. Take a car as an example. What are expectations from Car? Start the car. Accelerate the car. Brake. Move to reverse slowly. Stop. That’s it. To achieve these behaviour, you are provided wi...
Let us try to understand a little about all these, through a simple example. Human Beings are living forms, broadly categorized into two types, Male and Female. Right? Its true. Every Human being(Male or Female) has two legs, two hands, two eyes, one nose, one heart etc. There are ...
As example, we can have class Student. Object An object is aninstanceof a class. If a class is a logical entity, instances considered "real" - since it'sa realizationof a class. All the instances of a class shared similar properties, and have same behavior, as described in the "prototy...
In the above example, a getter can also be written using Fat Arrow function syntax like below but without any arguments. StringgetfullName=>"${this._firstName} ${this._lastName}"; Object An object is a real-life entity such as a table, human, car, etc. The object has two characteri...

Although there’s almost never a need to actually write a calculator in real life (except for homework assignments), I hope you enjoyed the article and got the gist of it — not how to calculate stuff, but how to go about solving a particular problem in a way that keeps your code ...
