I had to go with cut-and-paste.

The usual solution in Java is to factor out an API into an interface and
have several implementations of that interface. See Callable for
example - this basically encapsulates a "function" with no arguments and

In part it's the price you pay for static typing (somewhere all those
type names have to appear). Tools are good enough these days to offload
you from most of the hand typing via completion. If you have not yet
used a modern IDE yet you should really try Eclipse or NetBeans both of
which are free of charge.

If you look for a language on the JVM with less overhead maybe Scala is
for you. Some people do find it too compact though.
