An object oriented system is implemented to organise further information about each worker’s attendance. Classes, objects, methods and attributes are used in this system.
Each worker has a name and an attendance figure which can be between 0 and 100.
Write a definition for a fully encapsulated customer class, providing both get and set methods for all attributes. You do not have to write code for the constructor method.
