An int uses 32 bits of memory, a short uses 16 bits and a byte uses 8 bits. If you're only looping through 20/30 objects and you're concerned about memory usage, use byte instead.

Catering for memory usage to this level is rarely required with today's machines, though you could argue that using int everywhere is just lazy. Personally, I try to always use the relevant type that uses the least memory.
