How can I "pack" 3 digits into a single number, within a given range?

I am trying to condense 3 numbers, all of which lie within the range of -50 million to +50 million. How can I condense all 3 into a single number and then retrieve the 3 numbers again from un-condensing the single number.

For example if I have: -3000, 122, 103 will become a single number such as "9484010392"

Uncondensing "9484010392" will return [-3000, 122, 103]

The number 9484010392 is just chosen at random and serves no connection to the numbers in the example, it's just to clarify what I mean by a single condensed number.

etc.

P.S. Writing the program in Java :)
