Switch Statement assistance

Question

I have to write a program that uses the switch statement and asks the user to select one of three TV models. The programs provides a description of the models. Use the switch statement, display the model chosen, the description and the price.The user should make a selection by model number: The default is "Your choice is not available!"
I am not 100% sure that I wrote this program correctly with the switch statements and according to the guidelines set forth and would appreciate it if somebody could look it over and see if it looks correct and if not what needs to be addressed. Also, I'm getting an error when I compile (error information at the bottom of the page) and am unsure what needs to be changed to rectify this. Thanks a lot for the guidance.

String modelString = "0";
model = Integer.parseInt(modelString);You haven't shown the input dialog yet! Move the parsing to after you've updated modelString.
