ATM-Interface

ATM Interface in Java The ATM interface is a Java application designed to provide a user-friendly and efficient experience for managing banking transactions. It incorporates the principles of Object-Oriented Programming (OOP) to organize the code into modular and reusable components.

1. User Authentication: Users can securely log in using their unique credentials. Object-oriented design ensures encapsulation and protection of sensitive user information.

2. Transaction Management: Supports various transactions like balance inquiry, cash withdrawal, deposit, and fund transfers. Utilizes OOP principles such as encapsulation to keep transaction details private.

3. Heap Sort for Transaction History: Implements heap sort to efficiently organize and display transaction history. Ensures quick retrieval and display of recent transactions.

4. Account Management: Users can manage their account details, including updating personal information and changing PINs. Encapsulation and inheritance are employed to create a robust account management system.

5. GUI (Graphical User Interface): Employs Java's Swing or JavaFX for a user-friendly graphical interface. Adheres to design principles for a clean and intuitive layout.

6. Concurrency and Security: Utilizes OOP concepts such as multithreading for concurrent processing of transactions. Implements security measures to protect against unauthorized access and transactions.

7. Code Organization: Classes like User, Account, and Transaction follow OOP principles. The HeapSort class handles sorting of transaction history using the heap sort algorithm.

8. Conclusion: The ATM interface in Java showcases the power of object-oriented design, ensuring modularity, reusability, and maintainability. The integration of heap sort enhances the efficiency of managing transaction history, providing users with a seamless and secure banking experience.
