Why I cannot add ArrayList directly to Jlist?

Question

i am trying to add ArrayList to Jlist, but the only way that I given to understand is that to write the code like this :

ArrayList labels = new Arr         


        

Answer 1

Because JList doesn't have a constructor that accepts an ArrayList (or a List). It can only accept an array, a ListModel, or a Vector. See the documentation.

An ArrayList is not an array. You can't pass an ArrayList to a method that wants an array.
