Welcome back after long overwork and vacation period
Let’s start small, it’s still almost summer.
Bytes in java are always signed and are quite horrible to use because of the casting and weird side-effects (or I’m just stupid enough to call it weird).
But we need unsigned bytes quite a lot. Most of the time for reading various streams (networks, 8bit strings etc) some text stream you still end up with byte streams.
There is a nice trick converting them from signed to unsigned in case you want to get normal 0..255 range for the chars.
byte mybyte = -104;
long mynewint = mybyte & 0xFF;
Hope it helps!
I had quite a nice puzzling while trying to find some easier way. Is there?
