Correct use for Switch? Menu option order a Sandwich OR Salad

Good Morning/Afternoon,

Below is a the code I've written for my Java class ( As in school homework ). I'm not here trying to get someone to do the homework for me.

My question is: Can the switch/case be used how I have it set? Prompt user for input 1 or 2. Answer 1 they are getting a sandwich, answer 2 they are getting a salad.

The instructions for this program starts with the customer will order a sandwich or a salad. Then proceed to add toppings for an additional charge and can decline extra toppings as well.Then print out the order and total. The professor specified to use IF statements and the Switch. However, I have a feeling I am missing something because it looks like the Switch is the replacement of the IF statements in the examples I've found on Stack. Thank you for any and all assistance!
