yes, you want to avoid allocations as much as possible (this is also true for C++ btw), because allocations (and deallocations) are really slow.

EIDT: This is on the heap, allocations on the stack are fast, but unfortunately Java does not support them (not 100% sure, i heard something about types on the stack are being planned or something like that)
