Declaring an ArrayList

Question

Hi,
Being a total newbie I would like to kown how to declare an ArrayList to hold objects of a certain class?
I have a class called CraftItem how do I declare an ArrayList to hold objects of this class so I can use the methods in that class?
Thanks

// ... add some elements to the list ...
for (CraftItem item : list) {
    item.someMethod();
} If you're on <= 1.4, then there's nothing built in to let you specify the type of the list's elelments. Normally you'd just use a list and cast the reference you retrieveList list = new ArrayList();
// ... call add() a few times ...
for (Iterator iter = list.iterator; iter.hasNext();) {
    CraftItem item = (CraftItem)iter.next();
    item.someMethod();
