Output ArrayList to String without [,] (brackets) appearing

Question

OK, so I have an ArrayList that I need to return as a String. Right now I am using this approach:

List customers = new ArrayList<>();
L         


        

Answer 1

If you want your output to look like: item1, item2, item3

Arrays.toString(customers.toArray()).replace('[', ' ').replace(']', ' ').trim()

If you want your output to look like: item1 item2 item3

Arrays.toString(customers.toArray()).replace('[', ' ').replace(']', ' ').replace(',', ' ').trim()
