sorry about the subject - i'm not quite sure what it is i'm asking is called

is there anything wrong with doing this...?

ArrayList al = new ArrayList();
al.add(new MyClass(1, 2, 3, 4)); <-----

or is it better to do this?

ArrayList al = new ArrayList();
MyClass class = MyClass(1, 2, 3, 4);
al.add(class);

also if the arraylist is instantiated using generics as such

ArrayList<MyClass> al = new ArrayList<MyClass>();

does that mean that al.get() will return a MyClass or do i still have to
cast it?

TIA
