The classes 'Call' and 'Videocall' are defined in the attached programme.
See the definitions of the classes.

Then type the method
public static ArrayList<VideoCall> jamesCalls(ArrayList<VideoCall> calls)
which takes a list of video calls as its parameter.


The function of the method is to create and return a new list, to which only those calls are added from the original list where
one of the persons is named "James Bond"
the call has video on it.
The order of the calls must follow the order of the original list.
