java.lang.ArrayIndexOutOfBoundsException: -1
at farmersmarket5.Produce.addProduce(Produce.java:194)

Look at line 194 in the Produce program. You have used an index with a value of -1
which is not a valid value for an index.
You need to test the index's value before using it to make sure it is valid.
