## Overview

This is a Java Swing banking application. A user works through the desktop form to register or log in, then can manage a profile and account, add or withdraw/deposit funds, transfer to beneficiaries, and view statements. Main assembles the UI and domain services; those services use a shared database operations layer backed by a MySQL connection. The excerpts show selected calls, while several modules are represented only by SOURCE INDEX references, so their internal interactions are left unverified.

Main entry points: [`src/Main.java`](https://github.com/mh06a/bankmanagement-java/blob/master/src/Main.java) (Application bootstrap), [`src/BankForm.java`](https://github.com/mh06a/bankmanagement-java/blob/master/src/BankForm.java) (Banking form), [`src/DatabaseOperations.java`](https://github.com/mh06a/bankmanagement-java/blob/master/src/DatabaseOperations.java) (Database operations), [`src/BankAccount.java`](https://github.com/mh06a/bankmanagement-java/blob/master/src/BankAccount.java) (Bank account)
