Can a method with arbitrary number of arguments, be called with an array?

I would like to call a method which signature is

public void foo(Object object, Object ... objects) { }

and I call it like

Object[] objects = ...;
foo(objects);

as the compiler does'nt complain it seems valid, but what happens with the first parameter in the signature? Is it objects[0]

Can anyone explain the Object ... objects parameter, what happens internal?

I can't change the method, it's from Method class.
