reflection - Detecting whether a method/function exists in Java -

-

is there method/function in java checks if method/function available function_exists(functionname) in php?

here referring method/function of static class.

you can find out if method exists in java using reflection.

get class object of class you're interested in , call getmethod() method name , parameter types on it.

if method doesn't exist, throw nosuchmethodexception.

also, please note "functions" called methods in java.

last not least: keep in mind if think need this, chances you've got design problem @ hand. reflection (which methods inspect actual java classes called) rather specialized feature of java , should not used in business code (although it's used quite heavily , nice effects in common libraries).
