Switch statement with returns -- code correctness

I would take a different tack entirely. Don't RETURN in the middle of the method/function. Instead, just put the return value in a local variable and send it at the end.

Personally, I find the following to be more readable:

String result = "";

switch (something) {
case 0:
  result = "blah";
  break;
case 1:
  result = "foo";
  break;
}

return result;

Remove the break statements. They aren't needed and perhaps some compilers will issue "Unreachable code" warnings.
