this question has answer here: difference between int[] array , int array[] 25 answers i'm trying head around piece of code found. firstly, i'm not sure why code appears like: byte z[] = new byte[5]; instead of: byte[] z = new byte[5]; i mean, byte z[] not there declare array of bytes ? or code doing else? secondly, why choose bytes on doubles or ints . seems byte number -128 127. what's point in choosing on double ? byte[] z equivalent byte z[] 2 different methods of represent same. note java code conventions of sun (before becoming oracle) propose use first on second. preferreable use byte[] z = new byte[5]; instead of byte z[] = new byte[5]; for second part of question. byte uses 1 byte char uses 2 bytes int uses 4 bytes long uses 8 bytes so best use smallest numeric type avoid memory occupancy.
