Objective: Write a TimeObserver interface.
Define an interface (Java) or abstract class (C++) called
TimeObserver that has the following structure:
The provided graphic shows a class diagram for a class named TimeObserver. Here is a description of the diagram:
-
Class Name: The class is named
TimeObserver, as indicated in the top section of the diagram.
-
Method: The class contains one public method:
+timeChanged(newTime: int): void
+: This symbol indicates that the method is public.timeChanged: This is the name of the method.newTime: int: This indicates that the method accepts a single parameter named newTime, which is of type int.: void: This indicates that the method does not return any value (return type is void).
-
Purpose: The diagram implies that the
TimeObserver class is likely part of an Observer Design Pattern where it monitors or observes changes in a time value. When the time value changes, the timeChanged method is invoked with the updated time as its argument.
