Objects and classes form the basic structure of Object-Oriented Programming (OOP).

Mark scheme

Marking points from the official mark scheme (Oct/Nov 2024). The mark or mark type is shown in brackets.

1. [3] One mark per mark point (Max 3)
2. [3] MP1 Attributes/properties ...
3. [3] MP2 ... with their data types // ... are variables bound to the class
4. [3] MP3 Methods ...
5. [3] MP4 ... that are subroutines / functions / procedures that act upon the attributes
6. [3] MP5 Getters/setters ...
7. [3] MP6 ... are methods that can fetch / update the contents of attributes
8. [3] MP7 A constructor ...
9. [3] MP8 ... that is used to create instances / objects of this class.
10. [3] One mark per mark point (Max 3)
11. [3] MP1 A class is only defined once but many objects can be created from that class // A class is a template / blueprint from which objects are created // An object is an instance of a class
12. [3] MP2 No memory is allocated when a class is defined, but objects are allocated memory space whenever they are created
13. [3] MP3 A class cannot be manipulated as it is not available in the memory, but objects can be manipulated
14. [3] MP4 A class is defined but an object is declared / created / instantiated.
15. [3] MP5 A class can use inheritance. An object cannot.
