Create Bank.java

This code represents a simple banking application that allows customers to perform various banking operations

It defines a class Account that represents a bank account with attributes like balance, previous transaction, customer name, and customer ID. The class includes methods for depositing, withdrawing, and viewing the previous transaction.

The start method in the Account class serves as the main interaction point with the user. It displays a menu of options for checking the balance, depositing, withdrawing, viewing the previous transaction, and exiting. It repeatedly prompts the user for their choice until they choose to exit.

The Bank class is the main class of the program. It creates three instances of the Account class, each representing a different customer's account.

Users are prompted to enter a PIN, and based on the PIN entered, one of the customer accounts is accessed using the start method.

The program provides a simple text-based interface for customers to interact with their accounts.

It demonstrates basic object-oriented programming principles and user interaction with a console-based banking application.
