Determine an alternative to arraylists using strings

Assignment Help JAVA Programming
Reference no: EM131141710

I am working on an assignment to create a vending machine simulator. I have found a number of similar examples online but many of them use ArrayLists, which are not allowed for this assignment. I am attempting to determine an alternative to ArrayLists using strings and arrays. Additionally, one of the conditions of the assignment is that I have to support using a file (perhaps a comma delimited text file) to populate the vending machine inventory. I will also likely use the same approach to populate the coin and bills side of the problem.
