Question
I need to complete a java application that shows orbital fractals with two different colors. Below are directions:
This is the first part of a two-part project.
You will be working on an applet/application that draws a family of orbital fractals. (Orbital fractals are formed by using a function that repeatedly moves a point from place to place, and plotting a dot at each successive location of that point.)
Your first task is to complete the GUI by adding the appropriate Swing components and listener functors to duplicate the appearance and behavior of the sample solution (orbitalgui.jar) (There may be minor differences on differnet operating systems.)
Some notes:
