Thanks Thilo and Adam for the helpful information.

I'd like to understand a bit more on the quote "However, using large arrays
*will* increase the heap size". From my understanding, not all types of
arrays have their size impact the heap (Heap.heap) size. Specifically:

The sizes of the following array types *impact* the size of the heap:
  - integer and float (as the values will be directly stored in the heap)
  - String and other feature structures (as the address of each element
pointing to the related position on other heaps will be stored in the heap)

On the other hands, the sizes of the following array types do *not* impact
the size of the heap:
  - boolean, byte, short, long and double (as there are different heaps to
store the data)

Is my understanding correct?

Thanks,
Danai Wiriyayanyongsuk
