Summary: Learn how to implement a simple ATM system in Java, covering essential functionalities such as checking balance, depositing funds, withdrawing money, and handling user interactions.
---

In this guide, we'll walk through the implementation of a basic ATM (Automated Teller Machine) system in Java. This system will cover fundamental functionalities such as checking an account balance, depositing funds, and withdrawing money. We'll design it to handle user interactions through a console-based interface.

Setting Up the Project
To get started, create a new Java project in your preferred IDE. Once the project is set up, you can create the necessary classes and methods to implement the ATM system.

Class Structure
We'll create three main classes for our ATM system:

Account: This class represents a bank account and contains information such as the account holder's name, account number, and balance. It also includes methods for depositing and withdrawing funds.

ATM: This class acts as the main controller for the ATM system. It provides methods for performing transactions like checking balance, depositing funds, and withdrawing money.

Main: This class contains the main method and serves as the entry point for our program.

Implementing the Account Class
Let's start by implementing the Account class:

Running the Program
After implementing the classes, you can run the Main class to start the ATM system. You'll see a menu with options to check balance, deposit funds, withdraw money, or exit the program.

Conclusion
In this guide, we've built a basic ATM system in Java covering essential functionalities such as checking balance, depositing funds, and withdrawing money. This simple console-based implementation can serve as a foundation for more complex ATM systems with additional features and user interfaces.
