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 ?

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

You can find more details here

i do that in C#, so in JAVA what i need to do ?

I think you are looking for an unsigned byte? You might find something here.

@HảiDuyNguyễn Cast it to byte: byte[] Data = { (byte)0xA3, 0x34, 0x33, 0x33, 0x00};

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.
