NEED JAVA SOURCE CODE
This project is to develop an application software for ATM having a customer console (keyboard and display) for interaction with the customer, a printer for printing customer receipts, and a key-operated switch to allow an operator to start or stop the machine.
The ATM must be able to provide the following services to the customer: - 1. A customer must be able to make a cash withdrawal from any suitable account, in multiples of $20.00.
Approval must be obtained from the bank before cash is dispensed. (25 points)
- 2. A customer must be able to make a deposit to any account, consisting of cash and/or checks in an envelope. The customer will enter the amount of the deposit into the ATM, subject to manual verification when the envelope is removed from the machine by an operator. Approval must be obtained from the bank before physically accepting the envelope. (25 points)
- 3. A customer must be able to make a balance inquiry of any linked account. (20 points) A customer must be able to abort a transaction in progress by pressing the Cancel key instead of responding
to a request from the machine.
