box of produce JAVA CODE

Description:
* This program reads in three random vegetables from a predefined list and asks if the user would like
* to substitute any produce. The user can substitute produce as many times as they like.
* Once the user confirms the content of the box, the contents of the final box is output.

Description:

* It takes values from the file, "ListOfProduce," puts them into an array with numbers corresponding to each item.
* It produces three random numbers and accesses the corresponding value of the array.
