🏗 Java Concepts Demonstrated

Concept	Where
Classes & Encapsulation	Student.java — private fields, getters/setters
Interfaces	StudentDAO.java — defines storage contract
Inheritance	NavButton extends JButton, PanelCard extends JPanel
Exception Handling	All DAO methods, form validation, file I/O
File I/O	FileStudentDAO — ObjectOutputStream/InputStream
Threads	StudentListPanel.runTask() — background data loading
Collections	LinkedHashMap, ArrayList, Stream API
Generics	List<Student>, Map<String, Long>
Lambda / Functional	ThrowingRunnable, stream filters, action listeners
Swing Events	MouseListener, KeyListener, ActionListener
Custom Painting	paintComponent() in charts, cards, buttons
Serialization	Student implements Serializable

---

Data Storage

Data is saved to data/students.dat using Java Object Serialization. The file is created automatically on first run. Do not delete this file if you want to keep your records.

To reset all data: delete data/students.dat and restart the app.
