Can we make unsigned byte in Java

Question

I am trying to convert a signed byte in unsigned. The problem is the data I am receiving is unsigned and Java does not support unsigned byte, so when it reads the data it tr

Answer 1

If you want unsigned bytes in Java, just subtract 256 from the number you're interested in. It will produce two's complement with a negative value, which is the desired number in unsigned bytes.

Example:

int speed = 255; //Integer with the desired byte value
byte speed_unsigned = (byte)(speed-256);
//This will be represented in two's complement so its binary value will be 1111 1111
//which is the unsigned byte we desire.

You need to use such dirty hacks when using leJOS to program the NXT brick.
