Understanding Abstraction in Object-Oriented Programming

✨ LEARNING TAP Academy One of the fundamental pillars of Object-Oriented Programming (OOPS) is ABSTRACTION. 🔹 What is Abstraction? Abstraction is the concept of hiding implementation details and showing only the essential features of an object. 🔹 Abstract Class An abstract class is a restricted class that cannot be used to create objects. It acts as a blueprint for other classes. 🔹 Abstract Method An abstract method contains only the method signature (declaration) and no body (implementation). 💡 Key Points to Remember: ✔ An abstract class can inherit from another abstract class ✔ An abstract class can also inherit from a normal class ✔ A normal class can inherit from an abstract class ✔ An abstract class can have both abstract methods and concrete (normal) methods ✔ abstract and final keywords cannot be used together 💻 Example Program (Java): abstract class Animal { abstract void sound(); // abstract method void eat() { // concrete method System.out.println("Animal eats food"); } } class Dog extends Animal { void sound() { System.out.println("Dog barks"); } } public class Main { public static void main(String[] args) { // Animal a = new Animal(); ❌ Not allowed Dog d = new Dog(); d.sound(); d.eat(); } } 📌 Output: Dog barks Animal eats food ✨ Understanding abstraction helps you write cleaner, more secure, and maintainable code by focusing only on what is necessary. #Java #OOPS #Abstraction #Programming #TapAcademy #Learning #Coding
