Navigating Java functions?

[John Cooper]

I'd like to be able to bind a key to move to the beginning/end of the current
function, with repeated presses of the key taking me to the beginning/end of
successive functions in the buffer, i.e., ala {beginning,end}-of-defun that
works in lisp/C modes (but, fails in Java mode because functions typically
don't start at column 0).

I notice jde-which-method knows which function I'm in, so is it now possible to
add the beginning/end function navigation?

Thanks,
