- GUIDED PROJECT 1
- ATM Transaction Simulator with Receipt Logging (Console App)
- In this project, you will build a console-based ATM simulator that supports basic banking operations such as deposit, withdraw, and balance inquiry. Every transaction will be recorded in a persistent log file (CSV/text). The program will also generate a receipt file for a selected transaction or for the latest transaction. Finally, you will analyze the transaction log using Java 8 streams (e.g., total deposits, total withdrawals, count of transactions above a threshold). The project is designed to practice: exception handling (including custom exceptions), file reading/writing (append vs overwrite, CSV parsing), and Java 8 lambda/stream operations, along with debugging using IntelliJ breakpoints and watches.
