• Before you start coding, fill out an estimate form in PSP.

As you go, maintain a log of kinds and numbers of defects, and time spent in various phases of programming. When you're done (or along the way, if you prefer), enter these into the on-line PSP forms.
• For all the programming assignments, be sure to follow the design recipe. Each method should be documented, and each concrete class (and perhaps some abstract classes) should have a test method providing a good test suite for the class. Choose meaningful names for methods and parameters, and watch for opportunities to use methods you've already written. Be sure to test your program thoroughly before turning it in. If it doesn't work, tell me when and how it doesn't work, and what you've tried in attempting to solve the problem.
• Write an Applet that draws something interesting on the screen, using several of the following methods of the Graphics class:
  • drawLine()
  • clearRect()
  • drawArc()
  • drawOval()
  • drawPolygon()
  • drawPolyline()
  • drawRect()
  • drawRoundRect()
  • drawString()
  • drawString()
  • fillArc()
  • fillOval()
  • fillPolygon()
  • fillRect()
  • fillRoundRect()
  • setColor()
  • setFont()
  • repaint()
  Incorporate some kind of "memory", so that the picture on the screen is different each time the screen is redrawn.

  You can look up these methods at the on-line documentation for the Graphics class.
