ATM Interface

Project Overview

The ATM Interface is a console-based Java application developed using Object-Oriented Programming (OOP) concepts. This project simulates the basic operations of an Automated Teller Machine (ATM) and allows users to perform common banking transactions through a simple menu-driven interface.

Features

• Deposit money into the account
• Withdraw money from the account
• Check the available account balance
• Validate user input for invalid amounts
• Prevent withdrawals when the balance is insufficient
• Interactive menu-driven program

Technologies Used

• Java
• Object-Oriented Programming (OOP)
• Scanner Class for User Input

• BankAccount Class – Handles account balance, deposit, withdrawal, and balance checking.

How to Run

1. Open the project in VS Code or any Java IDE.
2. Compile the program using: javac ATM.java
3. Run the program using: java ATM
4. Choose the required option from the menu and perform transactions.
