I’m working on a Java question and need guidance to help me study.

Assignment Description

Your program must provide a menu to the user. This menu should list three different products of your choice. Once the user selects one product, they should specify which state they are located. The state choices should include CT, VT, WI, CA and WA. State taxes vary for each state (7.5%, 7.8%, 6.8%, 7.2% and 6.4%, respectively). The user should then specify the desired number of cases (assume there are 12 items per case). The appropriate state tax should be added to the total cost of the product (item quantity multiplied by unit price).

Name of the product selected
Number of cases
Number of items
Subtotal (units x price per unit)
