COMP 310 Fall 2011	Lec04: UML Diagrams

New Lab Times

• Mon. 12:35 PM - 1:50 PM

• Tue. 9:25 AM - 10:40 AM

Lab will be held in the Computer Lab in OEDK (Oshman Engineering Design Kitchen), which is located just off the North Parking Lot.

We will continue with our walkthrough from last lecture on building GUI's in lab today and tomorrow.

The HW01 due date has been moved back to Friday.

Quick UML primer:

• Boxes
  • Classes
    • Name, fields and methods
      • Concrete (regular type) vs abstract (italic type)
      • Chevrons sometimes used to denote interfaces.
      • Sometimes the "role" in which the class plays in the design will be also be noted.
    • Accessibility:  public (+), private (-), package (nothing)
  • Comments/Notes  (dog-eared)
• Lines:
  • Solid arrowheads -- generalization
    • solid line: inheritance
    • dotted line:implementation
  • Open arrowheads
    • solid line:  association ("has-a")  -- composition (with solid diamond end)  or aggregation (with open diamond end) or unspecified (no diamond end).   Java is always aggregation.
    • dotted line:   dependency ("instantiates", "uses", etc)

Use Green UML to help you concentrate on the design of your system, its structure and behaviors, rather than on the Java syntax.
