Connection and Collection Interfaces in Java
- by Bhupi
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.
