  • License plate number
  • Colour
  • # of doors
  • Speed (ReadOnly Property)
  • Maximum speed (ReadOnly Property)
• they also have 2 "Protected" methods:
  • Accelerate
  • Brake
• create the Vehicle class that has the above 5 private fields and 2 methods
• then create a stub program (like my bicycles one) that creates 2 vehicles, changes their fields and gives back their state

• read over and do the questions asked in Lesson 1 below
  • do the Airplane class in code
• once done, then look at Lesson 2 and the answers

Extra

• work on weekly assignment
