Declare byte[] in java?

Question

i try :

byte[] Data = { 0xA3, 0x34, 0x33, 0x33, 0x00};

but at "0xA3" it said "required byte found int",so what's problem here ?

`byte`s range from -128 to 127. `0xA3` is 163. – Mike M. Mar 22 '16 at 03:14 — Mike M., Mar 22 '16 at 03:14

0xA3 is 163 which is out of bounds for byte which I think can be -128 -> +127.

I think you are looking for an unsigned byte? You might find something [here](http://stackoverflow.com/q/4266756/2650847). – Matthew Wright Mar 22 '16 at 03:26

@HảiDuyNguyễn Cast it to byte: `byte[] Data = { (byte)0xA3, 0x34, 0x33, 0x33, 0x00};` – Andreas Mar 22 '16 at 03:26

The problem is that the range of a byte in Java is -128..127.

The solution is that you need to write a (byte) cast in front of 0xA3.
