Task 1

ATM Interface using Java Swing

📌 Project Overview

This is a Java Swing-based ATM Interface that provides essential banking functionalities such as user authentication, balance inquiry, deposits, withdrawals, PIN changes, and secure data management. The application uses file handling to store user credentials and account balances, ensuring persistent data across sessions.

🚀 Features

• User Authentication: Secure login system with username and password.
• New User Registration: Allows users to register with a username, password, and initial balance.
• Account Management:
  • Check balance
  • Deposit funds
  • Withdraw funds (with insufficient balance check)
  • Change PIN
  • Logout
• Persistent Data Storage: Uses a text file (users.txt) to save user credentials and account balances.
• Graphical User Interface (GUI): Built using Java Swing for an interactive experience.

🛠️ Technologies Used

• Java (JDK 8+ recommended)
• Swing (for GUI development)
• File Handling (for storing user data)

📥 Installation & Setup

1. Clone the repository:

   git clone https://github.com/your-username/ATM-Interface.git

2. Open the project in an IDE (Eclipse, IntelliJ IDEA, or VS Code with Java support).
3. Run the ATMLoginScreen.java file.
4. Create an account or log in with existing credentials.

📌 Usage

• Login with a registered username and password.
• If you are a new user, click "Register" to create an account.
• Once logged in, select an option:
  • View balance
  • Deposit money
  • Withdraw money
  • Change your PIN
  • Logout to return to the login screen

🔒 Security Considerations

• Passwords are currently stored in plain text in users.txt. For enhanced security, consider hashing passwords (e.g., using BCrypt).
• Ensure the application runs in a controlled environment to prevent unauthorized access to the user data file.
