Answer to Question #273635 in Java | JSP | JSF for Memo

Question

On the form, create two combo boxes, to allow a user to select between three

different printers and years. When a user has selected a printer and year and clicked

the submit button, display the amount of ink cartridges used for that year. Use the

following table for the printers and yearly cartridges used:

2018 2019 2020

HP Deskjesk 650 10 35 20

Epson K750 15 22 12

Canon Z100 30 31 33

Q.1.2 You are also required to create a menu system which will allow the user to exit the

application under the file menu. Under the tool’s menu, allow the form submission

and an option to display the yearly ink cartridges used for each printer. The layout

of the form is left to your discretion. Marks will be allocated to the presentation and

effectiveness of the layout, but the following layout is displayed for your

convenience.
