Java generics and varargs

Question

I\'d like to implement a function with both generics and varargs.

public class Question {
    public static  void doNastyThingsToClasses(Class

        

Answer 1

OK, so finally I end up throwing the varargs away:

public class Question {

    public static  void doNastyThingsToClasses(Class parent, List> classes) {
        /******/
        for(Class clazz : classes) {
            System.out.println(clazz);
        }
    }

    public static class NotQuestion {
    }
    public static class SomeQuestion extends Question {
    }

    public static void main(String[] args) {

        ArrayList> classes = new ArrayList>();
        classes.add(Question.class);
        classes.add(SomeQuestion.class);
        classes.add(NotQuestion.class);
        doNastyThingsToClasses(Object.class, classes);

        ArrayList> clazzes = new ArrayList>();
        clazzes.add(Question.class);
        clazzes.add(SomeQuestion.class);
        clazzes.add(NotQuestion.class); // yes, this will _not_ compile
        doNastyThingsToClasses(Question.class, clazzes);

    }

}

The only flaw is the long code for populating the collection used to carry function's arguments.
