In java is it possible to pack a integer number that is expected not to be negative & be final (not overflow) into a short?

"Unsigned int" into a short and back. Is this possible? How to do it if so? Grrrr. I forgot how signed numbers are implemented. The question makes no sense. Thanks anyway. I was going to downvote myself, you can do it instead.
an 'unsigned int' has no meaning in java. You can be either talking about an integer that has only 'positive' values, but still in the int range (a 31 bit number), or a full 32 bit unsigned int, which has a range of 0->(MAX_INT*2) on java. Neither will fit in a java short. A java short is still a signed number, with a max value of 2^15-1
