MongoDB is a document-oriented NoSQL database, i.e., the fields can vary from document to document and the data structure can be changed over time. A document in MongoDB resembles an object in OOPS. If we are having large tables with a huge amount of data (up to millions), then we...
package com.journaldev.oops.abstraction; public class CarTest { public static void main(String[] args) { Car car1 = new ManualCar(); Car car2 = new AutomaticCar(); car1.turnOnCar(); car1.turnOffCar(); System.out.println(car1.getCarType()); ...
An object contains some properties and methods. We can hide them from the outer world through access modifiers. We can provide access only for required functions and properties to the other programs. This is the general procedure to implement abstraction in OOPS. 4. What are the different types...
Creating the Object: We use the constructor in the Main method to create a Person object called Mukesh. The name "Mukesh" and the age "35" are the properties of this object, which is an instance of the Person class. This C# program will produce the following when it runs: Upon creating...
