## Overview

This repository contains two console products: a banking system and a single-file Wordle game. The banking workflow accepts a selected action and account details, creates a transaction ticket (or check), delegates validation and account lookup to Bank, applies the operation to the appropriate account type, and prints a receipt. The README documents the random-access account storage and transaction flow; the excerpts show representative callers and account behavior, but not every Bank operation or account-file format.

Main entry points: [`BankAccounts8/src/main/java/Bank.java`](https://github.com/lowski7/projects/blob/main/BankAccounts8/src/main/java/Bank.java) (Bank operations), [`BankAccounts8/src/main/java/BankAccounts8.java`](https://github.com/lowski7/projects/blob/main/BankAccounts8/src/main/java/BankAccounts8.java) (Menu and handlers), [`wordleApp/src/main/java/WordleApp.java`](https://github.com/lowski7/projects/blob/main/wordleApp/src/main/java/WordleApp.java) (Wordle game loop), [`BankAccounts8/src/main/java/Savings.java`](https://github.com/lowski7/projects/blob/main/BankAccounts8/src/main/java/Savings.java) (Savings account)
