1. ACO 101 Instantiating Graphic Objects

2. Review: 4 Phases to the Development Lifecycle Inception (Analysis & Design) – Business Requirements Business Analyst Game designers – Technical Specifications Programmers Elaboration (Design) – Functional specification document – Project Manager Construction (Implementation) – Programmers – Animators/Modelers Transition (Testing and Deployment) – Programmers – Testers – Project Manager

3. Review: Object Oriented Abstraction : aka Entity Abstraction

4. Review: Identifying Classes During design, you need to identify the classes. Classes are used to model things: Tangible things in the design: nouns, such as – purse, mailbox, bank account, keypad, email message Users – Student, Administrator, Bank Manager Agents ("-er" or "-or" words) – Scanner, file reader, sentence reader, CSVreader – agents perform some operation (sentence reader) Events and Transactions – Button click, ATM Withdrawal, Register for Course are all events – transactions are uses for interactions between classes, usually contain info that doesn't "belong" in a thing class

5. Identify the modules and abstract

6. Review… UML Class Diagrams [a visual modeling tool] BankAccount name accountID balance getBalance( ) credit( double amount ) debit( double amount ) getName( ) A UML class diagram The methods = what it DOES The Class Name The attributes or state = what it KNOWS

7. Review: What a Sequence Diagram looks like

8. Moving forward: Why do you need to understand the graphic objects? 1. The business has no time and wants its technology to spontaneously generate visual reports to give them data to make decisions 2. Data visualization is in its infancy 3. being able to abstract a problem effectively is a rare skill

11. Graphic objects to work with

12. The stage is an object

13. The paper that you used for your rectangle drawing is an object Paper = Stage – What is the same object as the paper? – Answer – the JFrame

14. JFrame: fields

15. JFrame: constructor

16. JFrame: methods

17. JFrame: more methods

19. Rectangle For a square use the rectangle and make the height and width the same value

20. Rectangle: The fields [holds the state]

21. Rectangle: the methods [what it does]

22. Rectangle: The constructor overloads

23. Homework Wiley plus code completion assignment: More Rectangles – If you seek help from the tutor – you must have class diagrams of the objects you intend to use to show to attain her help. Pick out the fields, constructor and the methods you intend to use in the Jframe and the Rectangle objects You must try to solve the problem by yourself before you ask the tutor for help. – You must also have a sequence diagram to show that you have tried to understand the relationship of the classes The computer lab is CLCC 385 and the tutor’s name and hours are posted on the Blackboard announcement post for this class
