ComboBox.setModel(   new javax.swing.DefaultComboBoxModel(carsArray)  )

Set up the array as a global variable.

References an arrayList in another class.  Set Model requires a string array.

String[] carsArray = new String[CarMain.cars.size()];

In constructor, before the initComponents()

        for(int i=0; i<carsArray.length; i++){

            carsArray[i] = CarMain.cars.get(i).carName;

Systems Development Life Cycle Notes

How do you plan a major, long term project?

  1. Analysis
  1. Will this require hardware, software or both
  2. What other systems (internal and external) will need to interact with this
  3. Determine the user groups and their needs
  4. Determine what are the problems with the old system
  5. Identify needed features for each user group
  6. Draw up a contract
  1. Design
  1. Plan from a coder’s perspective
  2. Breaking the code into “classes” (or chunks of code, features, etc.)
  3. Setting timelines
  1. Implementation & Testing
  1. Writing the code
  2. Building the system
  3. Ongoing testing, prototypes, alpha releases, etc.
  1. Deployment
  1. How are you going to release it?
  2. Do you need training for your customers?
  3. Marketing plan?
  1. Maintenance
  1. Updates?
  2. Bug fixes?

Two ways to implement it:

Case Study: EPSB’s Gradebook Software

Step

Analysis

Software only

Interactions: Scheduling software, Government reporting software

User group: Students, teachers, admin, parents, post secondary, government

Students & parents: Check marks

Teachers: Enter marks, Produce reports

Admin: Enter marks, Set up classes, Produce reports

Design

Plan java with a UML Diagram

Plan timeline with a Gantt chart

Implementation

Writing and debugging the code.

Testing

Thorough testing needed as beta tests not possible

Deployment &Maintenance

Train one school at each grade level

Those schools pilot for 1 year

All schools did training in May

Full rollout in September

New update when necessary

Go to this link and project it up:  looking at the Alberta Industry categories on this link. https://occinfo.alis.alberta.ca/occinfopreview/industries.aspx 

Once you have walked them through the website, have them open two documents via Google Classroom:

Please walk them through the assignment instructions. Note that it can be completed in partners and there is an extra section for partners that I will discuss with them next class

Give them the rest of the class to work on it. I expect most of it to be completed today but they will have about 30 minutes to finish next class.
