OOP Java Interview Questions & Answers

📝 OOP Java: A Brief Introduction 🚀

Welcome to the world of Object-Oriented Programming (OOP) in Java! 🎉

Here is a PPT attached for your reference which shows some most commonly asked question in OOP. So, have a look at this also 👇

🔍 What is OOP?

OOP is a programming paradigm that focuses on modeling real-world objects into software entities. In Java, everything revolves around objects! 🌟

💡 Key Concepts:

1️⃣ Classes: Blueprint for objects 🏠

2️⃣ Objects: Instances of classes 🌱

3️⃣ Encapsulation: Hiding data 🔒

4️⃣ Inheritance: Reusing code 🔄

5️⃣ Polymorphism: Many forms 🦄

6️⃣ Abstraction: Simplifying complexity 🎭

🔧 Java's Magic:

Java's OOP magic lies in creating classes, crafting objects, and establishing relationships between them. ✨

🌐 Sample Code:

```java

class Car {

  String make;

  String model;

  void startEngine() {

    System.out.println("Engine started!");

  }

}

public class Main {

  public static void main(String[] args) {

    Car myCar = new Car();

    myCar.make = "Toyota";

    myCar.model = "Corolla";

    System.out.println("My car is a " + myCar.make + " " + myCar.model + ".");

    myCar.startEngine();

  }

}

```

🤩 Conclusion:

Java's OOP is a fascinating world filled with endless possibilities. It enables us to create well-organized, scalable, and maintainable code. Happy coding! 💻
