how to read bytes bigger than 127 in java?

Question

alright, so my code to read bytes into a int is like so:

int offset = (byte << 16) | (byte2  << 8) | byte3;

And it's reading the bytes "00 00 be" as -66.

How do I read it as the 190 it's meant to be?

Answer 1

    byte b = -66;
    int i = b < 0 ? b + 256 : b;

It might be useful declare helper function for this.

Answer 2

byte b = -66;
int i = b & 0xff;
