Bank Web App – Class Project

Project Overview

This is a self-contained web or Android application that simulates a simple online banking system. It enables users to:

• Register a new bank account with an initial balance.
• Log in securely with a username and password.
• View current account balance.
• Deposit or withdraw funds from the account.

The goal of the project is to demonstrate understanding of full-stack development and secure user interactions.
