🚀 Java classes and methods are, why they matter, and how to use them effectively.
🔹 What is a Class in Java?
A class in Java is a blueprint and structure for creating objects. It defines:
📝 Properties (fields or attributes)
⚡ Behaviors (methods)
- A class defines the structure, while the object is created when the class is instantiated.
🏎 Example: Car Class
class Car {
String color;
int speed;
void drive() {
System.out.println("The car is driving...");
}
}
✨ Breakdown:
🚗 Car → the name of the class
🎨 color & ⚡ speed → instance variables (fields)
🛣 drive() → a method (behaviour)
🔹 Types of Methods in Java
There are 3 main types:
1️⃣ Instance Methods – Belong to objects of the class.
2️⃣ Static Methods – Belong to the class itself, no object needed.
3️⃣ Constructor Methods – Special methods to initialize objects.
🔹 Why Are Classes and Methods Important?
✨ Here’s why they matter in Java programming:
📦 Modularity → Divide programs into smaller, easier parts.
🔁 Reusability → Write once, use multiple times.
🔒 Encapsulation → Bundle data + methods for safety and organization.
🏗 Object-Oriented Design → Foundation of Java, helps build scalable apps.
🎯 Final Thoughts
Classes = Blueprints 🏗
Methods = Actions ⚡
✅ Organized
✅ Reusable
✅ Scalable
