8) JavaDocs

Head on over to the Documentation. You should know enough at this point to discover new functionality without me spelling it out.

Here is an example that takes advantage of several new methods.

Turtle bob = new Turtle();

bob.bgcolor("lightblue");

bob.penColor("red");

bob.width(10);

bob.speed(0);

for(int i=0;i<200;i++)

{

bob.forward(i/10.);

bob.left(5);

if(i%10==0)bob.dot("orange");//Draws dots when i is a multiple of 10.

}
