Software and Programming II
This module is a continuation of the studies presented in Software and Programming I focussing on the use of object-oriented methods for problem solving. Object-oriented programming languages require a different approach to software design from the traditional functional decomposition approach of procedural languages. Object-oriented systems are described in terms of independent objects, and their inter-relationships. Such systems can provide considerable potential for re-usability, extensibility, and robustness, assisting in the process of programming-in-the-large.
The Software and Programming I module has introduced students to the main concepts underlying object-oriented programming. The primary aim of the Software and Programming II module is to write maintainable object-oriented programs with an eye on the greater context of software development. On completion of the module, students should be able to design, document, implement, and test an object-oriented program consisting of several classes.
- Review of basic Java programming and the materials covered in Software and Programming I
- Objects and classes - Creating and manipulating objects. access modifiers: data hiding. Constructor methods and object creation. Static fields and methods.
- Passing objects and call-by-reference. Scope and the reference this. The qualifier final and class constants.

- Inheritance, polymorphism, and abstract classes - Overriding instance methods. The access modifier protected. The type Object. Inheritance and design. Abstract classes. Interfaces and multiple inheritance. The instanceof operator and casting non-primitive types. Parametric and ad-hoc polymorphism.
