You *could* have tried it for yourself, you know.
public class Jess {
public static void main(String[] unused) {
byte stone = (byte) 0xC9;
int paper = stone;
boolean scissors = (paper == 0x80000049);
System.out.println("Jess' prediction is " + scissors);
}
}
This sub-thread got started when you mocked javalaurence's use of
the word "effortlessly" in connection with Java bit-fiddling, suggesting
that you yourself considered it difficult. Others seem to have little
problem fiddling bits in Java, but in light of what you've posted I can
well believe your experience may differ.
Also, PLONK! because ignorance is curable but rudeness isn't.
