Hey all, im having a little trouble. basically im reading an array of integers from a file and putting it into a linked list, then from the linked list im transfering it to an array using the .toArray() method of the arrayList methods. the array is filled with the data, but when i call another method to display the array it is coming up with a null pointer error. ive used System.out.println to
test it and the array is of the correct size, and with the correct data in it in the method that reads the data into it, but outside of it the array is "empty" even though it is a global array?! it compiles absolutly fine but with a unsafe operation warning but that is not the issue. my code is below! much appriciated. Jeff.
