Question

I get a set of elements passed to my method without the type specified.

I want to find out what the class of the contained elements is… I know they’re all of the same type.

Tried:

Class c = set.getClass.getComponentClass();

But that probably doesnt work because it’s just for Array collections.

Answer 1

Set set = *method argument*;
Iterator iter = set.iterator();
while (iter.hasNext()) {
   Object object = iter.next();
   System.out.println(object.getClass());
}

Iterate over the elements in the set and print the class type, if you must. A set is a collection of elements.
