Fast Banking Simulator

Project Overview

A fast banking simulator built in Java using Object-Oriented Programming (OOP).
It allows users to create accounts, deposit and withdraw money, check balances, and maintain transaction history through a console interface.

Features

• Create Savings and Checking accounts
• Deposit and withdraw money with validation
• Check account balances
• Persistent storage using files
• User login system
• Data persists between program runs

Technologies Used

• Java SE
• OOP concepts: classes, inheritance, encapsulation
• Console input/output with Scanner
• File handling with File, FileWriter, BufferedReader, and Scanner

How It Works

1. Account Creation: User enters their name and chooses account type. An account number is generated and account data is saved to a file.
2. Login: Users enter their account number to access their account. Program reads the corresponding file to load account information.
3. Transactions: Users can deposit or withdraw money. Updated balances are written back to the account file.
4. Persistence: All account information and transaction data are saved in files. Users can log out and return later without losing their data.
