^What is happening here, it's creating an object of interface and monster class, not sure what this means.
/EDIT To be clear, ISaveable is an interface.


and again here, using List and ArrayList.. not sure what's happening. Thanks

Assuming that Monster implements ISaveable, and we already know that ArrayList implements the List interface.
All methods defined in those interfaces are available on objects of the type Monster or ArrayList, since they implement it, which is why you can do that.
