Apart from what has been already pointed out to you this code would'nt even compile. Using a variable which has not yet been assigned to is a compile time error.

You have initialized a single element array and added one value to it.
That one value is the value inside variable candidateID and is zero in this case.

Doesn't using an unassigned variable produce a compiler error? The only way I've seen this work is passing an unassigned variable into an out parameter.

Solution 1

What is does is create variable which can reference an array of objects, called param, assigns a new array array of objects (containing a single object) to it, and predefines the contents of that object array to a single integer (candidateID)

You end up with param referring to a single element array of objects which contains an integer.

This is a lot easier to explain with pictures...:laugh:

ok , so pls show the picture reference...

You forgot to mention that the int gets boxed into an Integer object, though I thoroughly doubt that OP would get the picture.
Oh wait you haven't supplied a picture yet :-P

I've drawn it - it's waiting here on my desk for him to come round and view :laugh:
