Passing null parameter list in getDeclaredMethod

[Dennis Putnam]

I am trying to use getDeclaredMethod and get a warning (not an error) when I try to pass null for my parameter list. I'd like to eliminate that warning but I can't seem to come up with the right syntax. The warning wants me to explicitly cast to Class<?> but everything I've tried results in an error.
This is the warning code:

caller.getClass().getDeclaredMethod("timerTriggered",null);

This is apparently what I need but can't get right:

caller.getClass().getDeclaredMethod("timerTriggered",Class<?>[] null);

Can someone give me the correct syntax? TIA.

It doesn’t want null. Try an empty array
(Class<?>[])new Object[]{}
instead.
By the way, what is giving you that warning? Is it an IDE?

[Campbell Ritchie]

You might not be able to cast that, in which case try
new Class[]{}
You may have to miss out the <?> or you might be able to cast it like this
(Class<?>[])new Class[]{}
You are not supposed to be able to create an array of a parameterised type.

Thanks for the reply and yes it is an IDE giving me that warning. Your solution (new Class[]{}) fixed it.

If you're using JDK 5 or later, you can take advantage of varargs - you don't need to explicitly create an array at all:

Method m = caller.getClass().getDeclaredMethod("timerTriggered");

Since there are no Class arguments, the compiler inserts code to automatically create an empty array, just as you did.
