Using Reflection - Method.invoke()

Question

Hi all,
Facing a problem in using the Reflection API. Can anyone tell me how to use the invoke, which is available with Method. Problem statement. - I want to create a method. And then invoke that method using method1. invoke. But this can take only the following arguments - (Object, Object [ ] ). I cant figure out why I need to pass on an object ? and an array of objects ?

If you read the docs for Method.invoke, you'll see that the first argument is the object on which you wish to invoke the method, and the second argument is the parameters (with primitives wrapped appropriately).
foo.bar("abc", 123);
// becomes
meth.invoke(foo, new Object[] {"abc", new Integer(123) }); (if I haven't screwed up the syntax of the array initialization)
