default arguments

Hi all!
I am working on some code for a frame grabber using the Java Native Interface. One method needs a boolean argument which tells whether or not to sync on the green channel, but ONLY if the input is RGB (as opposed to s-video or composite).
So my question is:
in C++, I could define a method with a default argument such as
int setConfig(int videoType, boolean syncOnGreen = false);
If the second argument is not provided, it defaults to false;
Is there an equivalent way of doing this with Java/JNI?
Thanks in advance.

There's no equivalent to the C++ shortcut to do it, but you can get the same effect by overloading the method:
