Overview
The ATM Machine Simulator mimics the functionality of an ATM machine, allowing users to authenticate and perform transactions.
Features
- Validation: Users must validate their credentials (ATM number and PIN).
- Transactions: Users can check balance, deposit, withdraw funds, and view a mini-statement.
Implementation
Key classes include:
- ATM Class: This class manages account details and operations.
- ATM Operation Interface: Defines the essential functionalities of an ATM machine.
- ATM Operation Implementation Class: Implements methods defined in the interface.
Source Code
Similar to other projects, source code can be accessed via GitHub or relevant code-sharing platforms.
3. Student Management System
Overview
This application enables educational institutions to manage student records effectively, including features for adding, updating, and deleting student data.
Features
- CRUD Operations: Manage student records through adding, viewing, updating, and deleting entries.
- Database Connection: The application connects to a MySQL database to persist data.
Implementation
