The folloing to java files input 5 objects into an array and can then be sorted by invoice number or price. Make the following two modifications:

1. Enhance the program by displaying a menu that asks the user how they want to sort the services menu. 1) Sort by Service Description, 2) Sort by Price, 3) Sort by Time (Minutes), or 0) to Exit.

2. Add a do...while() loop that keeps prompting the user for the next preferred sort order until the user finally chooses 0 to exit
