It's not hard to turn method calls into classes.

Anonymous inner classes--or perhaps not so anonymous--can do the job of
calling methods. How to actually get an instance of one is more nuanced
and requires more particulars.

One option might be to make the number you're switching on into an enum,
and then putting the methods into an EnumMap. HashMaps or arrays are
other possibilities. But without more specifics, that's really all I can
say.
