At one point you said this:

this is the only time you have really tried to say what you want to do. Is
this still what you want? Because if it is, it seems that you now have it.
If you have a Calendar object ie param, then you just get a Date object with
getTime(). If you want to format it then just do:

> >System.out.println(dd);

You can do all that manual concatenation you are doing, but the Format
classes make this unnecessary, hence the new pattern above: "M/d/yyyy hh:mm"

With the main you require to test just do:

public static void main(String[] args) {

    ThisClass a = new ThisClass();
    a.setRequestedDate(new GregorianCalendar());
}

but your setRequestedDate method is not setting anything!
Is this what you want to do? Set a Calendar object to a certain date?

Perhaps you could try to express clearly what you want to do!
