Splet13. mar. 2014 · The integer constant 32767 is, in hex, 0x00007FFF. A byte is a signed 8-bit type. Casting (byte)0x00007FFF effectively truncates the upper 24 bits, leaving 0xFF. Since it is signed, this represents -1. Assigning it back to a short doesn't change the value because it's already been converted to a byte, and -1 is within range of a short.
