It doesn't seem to be necessary to use the cast in the last of these.
E.G. the following works:
byte b = -10; int i = b & 0xff; System.out.println(i);
I'm guessing because the bit-operations work on and return ints.

int i byte b
b = (byte) i; // convert int to byte i = (int) b; // convert byte to int , b=-10 -> int = -10 i = (int) (b & 0xff) // unsigne b and convert it to int , b=-10 -> int = 245
ok ?

I think i find my way using the ByteArrayOutputStream.class. it look fine working with byte

Hi,===========================================================================
The answer to your problem is probably the native static method System.arraycopy()

Hi,
I know it is not the best place to ask this. But i do not know any other were people answer. I got a problem working with byte type in JAVA. i am use to C.
So i like to crete a struc byte toto byte[] size = new byte[10]; byte[] data = null; and i would like to copy this structure into another byte[]. but i find out that we cannot concatenate byte. and i did not find any method that allow me to copy into bytte[]. I do not want to use String to byte because of the problem of decode and coding. i findout that there is some trouble with it (back slash into blank).
Does some one could tell me how to do this:
copy the size into the byte[] then adding the data to the same byte[]. how to extract the 10 first byte from the byte[]
i really do not know how to solve this problem in JAVA.
One small example would be so nice
Thanks Herve
