Java Integer Literals Integer literals in Java can be used in three flavors in a Java program those aredecimal,octal(base 8), andhexadecimal(base 16). Octal literalsare specified in Java program by a leading zer

literals, which is at least consistent. In Sun's case it's actually a little better as the related code blocks using the constants are next to each other whereas in Harmony's the static definition is at the top of the class, far from the usage of the cache. gcj did replace all ...
We can, of course, store the bit pattern 0xFF in a byte (which byte has a value of -1 in Java). Remember integer literals are implicitly unsigned Eh? , but you must cast 255 to a byte, and it can be displayed as -1. ? 1 2 3 4 byte b = (byte)0xff; System.out.println...

So it looks like all integer literals appearing in code must be in the range -2147483648 to 2147483647. May the Moose be with you.Rolf Weasel Ranch Hand Posts: 82 posted 24 years ago even an explicit cast did'nt work: public static void main(String[] args) { long l = (long) 214...
