Answer 1

First you need to realise that a byte stores 256 values whether its signed or unsigned. If you want to get unsigned values from a signed byte (which is what Java supports) you can use & 0xFF

e.g.

byte[] bytes = { 0, 127, -128, -1};
for(byte b: bytes) {
  int unsigned = b & 0xFF;
  System.out.println(unsigned);
}

prints

0
127
128
255

The simple answer is you don't need a byte[] which has the same values. ;)
