Excelent reply. To simplify your code a bit, you might look at something
like:
int j=0;
String[] strings = new String[list.size()];
Iterator i = list.iterator();
while(i.hasNext()) {
strings[j++] = String.valueOf(i.next());
}
String.valueOf() will automatically convert everything (including Strings)
to Strings (if you don't mind "null" for null values).

Miro,
1. Please use your real name in your email address when posting to the
list. "temp temp" is a poor moniker.
2. While some of us will be happy to answer "purely" Java questions,
please mark such posts as [OT] (for "off-topic") and apologize
in advance. Otherwise, post to a generic Java mailing list.
In an effort to kill this question before it gets too far, I offer this
response:

Casting is easy. That's just not what you're asking... what you really
want to know is how to convert a List of objects into a String array.
The answer depends on what you already have in your List. For example,
this might work if all your list items are already strings.
String[] strings = (String[])list.toArray(new String[list.size()]);
But if not all your objects are Strings already, you'll get an
ArrayStorageException or something like that.
If you have non-string data in there, you'll have to do something more
intricate:
int j=0;
String[] strings = new String[list.size()];
for(Iterator i=list.iterator(); i.hasNext(); ++j)
{
Object item = i.next();
if(null == item)
strings[j] = null;
else if(item instanceof String)
strings[j] = (String)item;
else
strings[j] = item.toString(); // simple conversion; you might
// require something more exotic
}
Hope that helps,
