Which class implements all the Connection Interfaces which are in javax.microedition.io package and how?
And in the same way which class implements the some of Collection interfaces like Iterator interface.
I saw a code: -
Iterator it;
ArrayList list = new ArrayList();
it = list.iterator();
The iterator() return type is "Iterator" which is an interface.
Please tell me what this code is doing is it returning an object of type Iterator? but as far as I know, interface can't be initialized.
