TAILIEUCHUNG - Lecture Software construction - Lecture 4: Object-oriented design – key concepts

This chapter presents the following content: Examples of class diagrams; navigation, visibility, named associations, and multiplicity in UML; interfaces and implementation, in UML. In this chapter students will be able to: Students will have a strong conceptual foundation for their future uses of the OO features of Java, students will be able to interpret a class diagram, students will be competent at the basic OO design patterns. | Software Construction Lecture 4 Object-Oriented Design – Key Concepts 1 Agenda & Reading 2 Topics: Abstraction and information hiding Inheritance, instantiation, and polymorphism Association, aggregation, and composition Reading The Java Tutorial, on Inheritance Wikipedia, on Class Diagram Learning Objectives 3 Students will have a strong conceptual foundation for their future uses of the OO features of Java Inheritance (is-a) vs composition/aggregation/association (has-a) Polymorphism Students will be able to discuss the OO features of an existing design (as expressed in a Java program or a class diagram) Students will be competent at basic OO design Abstraction 4 An abstraction is a view or representation of an entity that includes only the attributes of significance in a particular context. Abstraction is essential when working with complex systems. Without abstraction, the programmer faces an overwhelming level of detail. Complex Object Idealised Model Ignore Inessential Details
