Answer to Question #263143 in Java | JSP | JSF for doeboy

Question

Develop a Java GUI application that will display the ink cartridge usage of three different printers with a time span of three years.

Q.1.1 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 Deskjet 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.

Q.1.3 The application must display a report of each printer and the total ink cartridge used for the three different years.
