I am trying to get more control on user input. I have written a couple of Exceptions to handle two different user inputs, but I want to program to retry it if it is invalid and allow the program to continue. I have tried using a labeled break and it did not work out right. I will post the source code below and made the sections in question in bold.

final variables. */

of the main. */
