In this lab, you are to take this almost completed Java program to draw Pascal's triangle. Here is a running version that draws one circle. Note that the parts that change colors and the number of rows R and the modulus N are already written. Your part is to fill in the drawing using this partially written program.

On your PC, the program JavaEdit should be running. It has two files loaded, Pascal.java and Pascal.html, as inidicated in the tabs at the bottom of the window.

1. Edit the file Pascal.java. Select that file tab and look at the program. Near the bottom of the file is a method called paint that does the drawing. Parts of this method have been filled in for you. You are to add the parts that define the array values and that defines x and y locations to draw the circles. Note that within the symbols /* and */ are "comments" that tell you what to do. Anything within these symbols are ignored as a program.
2. When you think your program is done, you will need to compile it. Go to the menu item called run and click on Compile. If there are errors in your program (and there are bound to be at first), correct them with the help of the instructor or TA's. Then compile again until it says that it compiled o.k.
3. Now select the Pascal.html tab. To view your applet, go to the menu item called run and click on Load in Browser. A window should come up to view your applet. How many rows can you view? Which colors do you like? Do the different mod numbers all work?
