Question

The method is public static void method(Object[] params), how should I call it in the following scenarios?

1. with one object as parameter ClassA a
2. with more than one objects as parameters ClassA a, ClassB b, ClassC c?
   thank you

Answer 1

You can create the array of objects on the fly:

method(new Object[] { a, b, c});

Another suggestion is that you change the signature of the method so that it uses java varargs:

public static void method(Object... params)

Nice thing is that it is compiled into a method with the same signature as above (Object[] params). But it may be called like method(a) or method(a, b, c).
