Classes, objects and methods

Classes, objects and methods are the building blocks of Java programs.

  • For this video, you can use the turtle-v1.zip project that you used in the previous lesson.
  • Follow along with the video below.
  • After the video, use the Quizlet to see what you remember.
  • Use the turtle object to make some designs. You can clear the screen by pressing the Reset button. This will also remove the turtle, so you'll need to add a new turtle to the turtle world each time you Reset. The screen is also cleared every time you quit out of Greenfoot and go back in.
  • When you're satisfied with your Quizlet work and your screen designs, go on to the next lesson.
