This environment, gives you access to the
full java.awt.Graphics
API. Your code’s draw method will be called with
a Graphic object, a width, and a height and can use any of the
methods on the Graphic object to draw an image. The image will
be generated and returned to this webpage and displayed on the right. You
should use the width and height arguments to make your code resilliant in
the face of changing window sizes.
Some things to try:
Draw a circle in the center of the drawing area whose size is some
fraction of the height of the drawing area.
Draw two circles, centered vertically, one 1/4 of the way from the left
side of the drawing area and the other 1/4 of the way from the right side.
Draw two circles that are just touching.
Draw a rectangle that exactly enclosed the two touching circles.
Whatever you want! Experiment with generative art or try to make something
representational. Be sure to read the docs linked above to find out what
all you can do with the Graphics object.
