CS 140 - Homework 3 Due Monday September 14

Create a new folder in your student folder on the T: drive named HW3 and copy a Program.java to the HW3 folder.

To see how your homework should finally look run my version by double clicking on My Computer and going to the folder T:/Harcourt/Fall09/cs140/HW3 and then double click on the file run.bat.

1. Use a loop to draw 50 concentric circles. Make the biggest circle 500 pixels wide and high. It should look like below.
2. Modify your loop above so it animates drawing the circles by starting with the outermost circle. Draw a new circle every tenth of a second. Do all of this in a method named drawCircles
3. Now animate erasing the circles from the inside out. The code is very similar to above but think about how you would reverse the process. Do this in a method named eraseCircles.
4. Now draw circles like we did initially but draw filled circles and animate them starting with the outer circle. Start the outer circle white and make each circle progressively darker. The final result should look like below. Do this in a method named fadedCircles.
5. Your run method should be fairly short and just call the three methods drawCircles, eraseCircles, and fadedCircles.
