Iterate through List and return (the names) of all the classes

Question

Hi,
I've got a List and want to see what kind of classes are in this List.
List list = getList();
Iterator it = list.iterator();
while (it.hasNext()) {
     Object ob = it.next(); // get the next item. Is this the right approach for my problem?
        // Her I want to check the Object what classses it holds,
        // assuming that this is the right approach for my problem
}Thanks

Hi,
that's what I did:
List list = getList();
Iterator it = list.iterator();
while (it.hasNext()) {
     Object ob = it.next(); // get the next item. Is this the right approach for my problem?
         Class cLass = ob.getClass();
         System.out.println("\t" + cLass.getName());
}This returned java.lang.Object as mentioned.
Question:
- Can an Object hold several types of classes? If so, how can I iterate them?
Mabe this makes things a little clearer:
Why am asking this? I'm returning a List from a (Hibernate)-query. I can access one Class without problems. Another class that should be returned, I can't access. Thats why I want to know what I'm dealing with.
Thanks
