Question

use java to design the application,

the GUI should appear as in the picture shown .

Use java language: Requirements Document A local bank intends to install a new automated teller machine (ATM) to allow users (i.e., bank customers) to perform basic financial transactions. Each user can have only one account at the bank. ATM users should be able to view their account balance, withdraw cash (i.e., take money out of an account) and deposit funds (i.e., place money into an account). The user interface of the automated teller machine contains: *a screen that displays messages to the user *a keypad that receives numeric input from the user *a cash dispenser that dispenses cash to the user and *a deposit slot that receives deposit envelopes from the user. The bank wants you to develop software to perform the financial transactions initiated by bank customers through the ATM. The bank will integrate the software with the ATM's hardware at a later time. The software should encapsulate the functionality of the hardware devices (e.g., cash dispenser, deposit slot) within software components, but it need not concern itself with how these devices perform their duties. The ATM hardware has not been developed yet, so instead of writing your software to run on the ATM, you should develop a first version to run on a personal computer. This version should use the computer's monitor to simulate the ATM's screen, and the computer's keyboard to simulate the ATM's keypad. * Be Sure to add Your First and Last Name on the Welcome Screen Automated teller machine user interface." • Also Add Your EMPLID at the Bottom of the Choices Screen "ATM main menu." * Submit both code and a report on PDF format.
