BankingApp

BankingApp is a simple Java-based console application that simulates basic banking operations, including user sign-up, login, deposit, withdrawal, and transaction history tracking. This project is designed to demonstrate core Java programming skills, file handling, and basic OOP principles.

Features

• User Sign-up and Login: Allows new users to register with a username, password, and initial balance.
• Secure Login: Validates credentials to ensure only registered users can access their accounts.
• Deposit & Withdraw: Users can deposit or withdraw funds, with updated balances.
• Transaction History: Maintains a record of each user's deposits and withdrawals.
• Data Persistence: User information, including balance, is saved to a file and loaded on subsequent logins.
• User Interface: Features a modern and intuitive UI for seamless user interaction.

Tech Stack

• Java: Core programming language
• Swing: For building the user interface
• File Handling: For storing and retrieving user credentials and transaction history
• Object-Oriented Programming (OOP): Utilizes classes and objects for modularity and reusability
