## Overview

MoneyMoneyBank is a small Java banking example with savings and current account types. Its demonstrated workflow starts at the Client entry point, constructs both account types, and invokes withdrawals that print account information. A factory API can create either account type, but the sample Client does not use it. The source shows no persistent state or external banking service; account behavior is implemented in memory. The graph reflects the supplied source excerpts, which do not include a README.

Main entry points: [`MoneyMoneyBank/src/com/amc/Client/Client.java`](https://github.com/nandu0925/bank_proj/blob/main/MoneyMoneyBank/src/com/amc/Client/Client.java) (Client entry), [`MoneyMoneyBank/src/com/amc/Application/MMSavingAcc.java`](https://github.com/nandu0925/bank_proj/blob/main/MoneyMoneyBank/src/com/amc/Application/MMSavingAcc.java) (MoneyMoney savings), [`MoneyMoneyBank/src/com/amc/Application/MMCurrentAcc.java`](https://github.com/nandu0925/bank_proj/blob/main/MoneyMoneyBank/src/com/amc/Application/MMCurrentAcc.java) (MoneyMoney current), [`MoneyMoneyBank/src/com/amc/Application/MMBankFactory.java`](https://github.com/nandu0925/bank_proj/blob/main/MoneyMoneyBank/src/com/amc/Application/MMBankFactory.java) (MoneyMoney factory)
