🧠 Core Topics Covered

• Classes, Objects & Encapsulation: Private fields, validation getters/setters, constructors, and copy constructors.
• Inheritance & Polymorphism: Abstract classes, interface implementation, method overloading, method overriding, and instanceof downcasting.
• Has-A Relationships: Object composition (e.g. Vehicle + Engine, Room + Amenity).
• Graphical User Interfaces (GUI): JavaFX FXML layouts, Controllers, Application lifecycle, and Event Handling.
• Containerization: Dockerfile configurations for Java applications.

⚡ How to Run

# Compile any single console file
javac FileName.java

# Run console app
java ClassName

For JavaFX projects (Smart_Student_Ranking_System & javafx/demo), run using Maven:

./mvnw javafx:run
