New to Java

I dunno why im getting this error but i think i properly typecast it...heres a portion of my program...
----------
ArrayList list = new ArrayList();

while (rset.next()){
int shares=rset.getInt("new_shares");
list.add(shares);
}

for(int i=0;i<list.size(); i++)
{
List new_list = (List) list.get(i);
System.out.println(list1);
}
