Java data type - byte

Question

Hi;
I've a question here, hopefully some one can help me to clear my doubt.
private byte[] buf = new byte[1024];
as the declaration done above, does that mean the buf can hold until 1024 bytes data? as i know, byte data type only able to hold +2 power of 8 till -2 power of 7.
YY.

Answer 1

private byte[] buf = new byte[1024];
as the declaration done above, does that mean the buf can hold until
1024 bytes data? Yep, you've just defined an array of 1024 bytes, all neatly lined up next
to eachother, the first byte can be retrieved or altered by indexing it like
this: 'buf[0]', the next one as 'buf[1]' and the last one as 'buf[1023]'.
as i know, byte data type only able to hold +2 power of 8 till -2 power of 7.Erm, almost; a byte can store any integral number in the range -128 to 127
inclusive, i.e. -2**7 to 2**7-1.
kind regards,
