Edit Question
Title
Body
It looks like arraylist is not doing its job for presizing: // presizing ArrayList<Integer> list = new ArrayList<Integer>(60); Afterwards when I try to access it: list.get(5) Instead of returning 0 it throws IndexOutOfBoundsException: Index 5 out of bounds for length 0 . Is there a way to initialize all elements to 0 of an exact size like what C++ does?
