The result of a library call is a byte primitive, which you can then assign to a private static final byte constant. From there on out, that will be as fast as a code literal. You are not considering the impact of constant folding on compiler optimizations. This might have been an issue years ago, but modern JVMs can handle this kind of thing easily. --tim It is still an issue for JavaME and "case" labels in switch statements. However the need for binary values in case labels must surely be very rare. I don't find the processor instruction simulation example to be very convincing.
