Java Final Case Study: A Banking System with Real-Life Features

Welcome to our YouTube video titled "Java Final Case Study: A Banking System with Real-Life Features"! In this video, we, University of Makati students, group 5 from grade 11-03CPG, will be presenting our final case study, a Java-based banking program that incorporates real-life functionalities.

This program is designed to provide users with a range of essential banking features, including balance inquiries, withdrawals, deposits, and fund transfers. Moreover, it includes administrative capabilities to effectively manage customer accounts. Join us as we delve into the code, exploring its structure and functionalities in detail.

To begin, the program imports essential Java libraries for input, output, and exception handling. The core functionality resides within the BankTransaction class, which contains various methods and logical operations for handling banking transactions. Account information is stored in a two-dimensional array named ACCOUNT_TABLE. We have defined constant variables such as MAX_ATTEMPTS and SERVICE_FEE to enhance the program's functionality.

The main method initiates the transaction process by calling the displayMenu function. Within this function, users are presented with a main menu where they can choose to either start a transaction or exit the program. When a user decides to begin a transaction, they are prompted to enter their account pin number. The entered pin is then validated against the entries in ACCOUNT_TABLE. If the pin number is invalid, the program displays the message "The account doesn't exist" and returns to the main menu. Valid login credentials grant access to the transaction menu.

The transaction menu offers a range of actions, including balance inquiries, withdrawals, deposits, fund transfers, and cancellations. The processTransaction method handles these specific transactions, interacting with users to gather the required information. Following each transaction, users can choose to exit the program or continue with additional transactions.

For administrative purposes, an additional menu called displayAdminMenu is available exclusively to the administrator. This menu provides options for managing customer information and exiting the program. Administrative tasks, such as viewing customer information, adding new customers, editing customer details, and changing customer PINs, are handled by various methods. These methods interact with users to collect the necessary information and fulfill the requested actions.

To provide a comprehensive demonstration, I will execute the code, showcasing the output and explaining the outcomes based on the choices I make during the program's execution.
