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

Adamski provided the best answer, but it is not quite complete, so read his reply, as it explains the details I'm not.

If you have a system function that requires an unsigned byte to be passed to it, you can pass a signed byte as it will automatically treat it as an unsigned byte.

So if a system function requires four bytes, for example, 192 168 0 1 as unsigned bytes you can pass -64 -88 0 1, and the function will still work, because the act of passing them to the function will un-sign them.

However you are unlikely to have this problem as system functions are hidden behind classes for cross-platform compatibility, though some of the java.io read methods return unsighed bytes as an int.

If you want to see this working, try writing signed bytes to a file and read them back as unsigned bytes.
