error when adding to Jlist from arrayList

I am trying to make a program that takes the number of students that are going to be graded and then get the x number of grades and bubble sort them in ascending order.

I am not sure how to add the grades from the arraylist to jlist and output it. this is my error:

Unresolved compilation problem: 
    The method setListData(Integer[]) in the type JList<Integer> is not applicable for the arguments (Object[])

This is my code:
