No reason to re-implement all that stuff yourself. There are good solutions for reading primitive values from a byte stream. NIO `ByteBuffer`s are one, there is ByteArrayDataInput from Guava, etc.

About Guava, Are there real benefits using unsignedBytes instead of simply promoting byte to int? I've to work with a lot of unsigned values

[diesieben07]

Well, there is a difference. 0xFF.toByte().toInt() == -1 But UnsignedBytes.toInt(UnsignedBytes.checkedCast(0xFF)) == 255.

[manuell]

Well, 0xFF.toByte().toInt() and 0xFF == 255

[diesieben07]

No, 0xFF.toByte().toInt() == -1.

[manuell]

Yes, but You've to add a bitwise AND

[diesieben07]

Yes, which is what UnsignedBytes does.
