Project Overview

This project is a console-based ATM interface implemented in Java. It consists of five different classes to manage different aspects of the application:

• ATM: The main class that handles user interactions and menu options.
• UserAccount: Manages user account information, such as User ID, User PIN, and Available Balance.
• TransactionHistory: Keeps a record of user transactions, including transaction type, amount, and available balance.
• DatabaseManager: Handles database connections and SQL operations.
• InputHelper: Provides utility methods for user input validation and formatting.

Features

• User Account Management: Create and manage user accounts with User ID, User PIN, and Available Balance.
• Transaction History: Keep track of transaction history, including transaction type (withdrawal, deposit, transfer), transaction amount, and available balance.
• Withdrawals: Users can withdraw funds from their account.
• Deposits: Users can deposit funds into their account.
• Fund Transfers: Users can transfer money between accounts.
• Quit: Exit the ATM interface.
