depends if you want the valkues or keys.
to get the keys use:

ArrayList list = new ArrayList(ht.values());

to get the keys:

ArrayList list = new ArrayList(ht.keySet());

One question what is the differnce between

using constructor
ArrayList list = new ArrayList(ht.values());

and typecasting
ArrayList list = (ArrayList ) ht.values();

Creates a new instance of ArrayList

Assigns list to the collection returnurned by values().
This will only work if the return instance is an instance of ArrayList (which I'm pretty sure it's not).

So is typecasting is only used when return type is of object and of other primitive types like char to int is it?

Mick BarryJava DeveloperCommented:
eg. if you have an ArrayList containing Strings':

String s = (String) mylist.get(0);
