✅ *Quick Recap of Java Classes & Objects* ☕🧱 1️⃣ *What is a Class?* – A *blueprint* for creating objects. – Defines properties (fields) and behaviors (methods). 2️⃣ *What is an Object?* – An *instance* of a class. – Created using the `new` keyword. 3️⃣ *Class Structure Example:* ```java class Car { String color; void drive() { System.out.println("Driving..."); } } ``` 4️⃣ *Creating an Object:* ```java Car myCar = new Car(); myCar.color = "Red"; myCar.drive(); ``` 5️⃣ *Constructor:* – Special method to initialize objects. ```java Car(String c) { color = c; } ``` 6️⃣ *Types of Classes:* – Regular, Abstract, Final, Inner Class 7️⃣ *Object-Oriented Principles in Action:* – *Encapsulation*: keeping data private – *Abstraction*: exposing only necessary methods – *Reusability*: via objects and inheritance 8️⃣ *this Keyword:* – Refers to the current object instance. 9️⃣ *Static vs Instance:* – *Static* belongs to the class – *Instance* belongs to the object 🔟 *Object Lifecycle:* – Created → Used → Eligible for Garbage Collection 💬 *Tap ❤️ for more!*
