Casting problem of Arraylist

[garfild Baram]

Hi,
I have an Arraylist that contains hashtables, trying to retrieve those hashtable using:
Hashtable hash=null;
hash = (Hashtable)arr(0);
I get ClassCastException (although the compilation goes well).
How do I cast an Arraylist to get my hashpapies??
Thanks

What does "arr(0)" do? What type does it return?

[garfild Baram]

All objects in the ArrayList are Hashtable type and arr(0) should return first Hashtable inserted.

Hello!
I do not understand yout expression arr(0) as well. Is it possible to post more line of code?
Other option: Does it look like this:

  
import java.util.*;
public class ArrayTest {
    public static void main(String args[]) {
        ArrayList arr = new ArrayList();
        arr.add(new Hashtable());
        Hashtable hash = (Hashtable) arr.get(0);
    }
}

This one works. Greetings from Hamburg,
Stefan
