Revised Splat Project

The assignment is to modify the Splat program by adding a label to each Circle object and storing them in an ArrayList. The user should be prompted for the number of circles they want, and then the program will generate that many random circles with unique names and colors.

Assignment #10
Two projects: Programming Project 6.22 and the following modification to the Splat
program.
Splat, Revised
Start with the "Splat" program from Ch. 4, Listings 4.7, 4.8, and 4.9. Create a Java project
with these three files, and run it to be sure it works.
Modify the program so that each Circle object has a label that it stores and displays (when
drawn via its draw()) method. You can assume that the label is a very short String that will
fit in the Circle. Test that your program works by modifying SplatPanel to give the circles
names. (You can change the circles to be not filled-in and draw the text in white as in the
next figure.)
Here's the fun part: modify the SplatPanel program so that instead of storing and creating
and drawing five arbitrary Circles, it generates n random Circles and stores them on
an ArrayList. Prompt the user via a dialog box for the number of circles. This entails a lot of
things:
 Use of the dialog box to prompt for and retrieve the number of circles.
 Replacing the five Circle instance variables with a single ArrayList instance variable.
 Writing a loop that generates the appropriate number of random Circles. Be sure to
generate circles that fit on-screen! Use appropriate logic on the random number generation
to be sure.
 Use the index of the loop to "name" each Circle.
 Generate random colors like this:
 Color color = new Color(generator.nextInt(0xffffff));
(where generator is your Random object).
 Modify the paintComponent() method so that instead of trying to print the five
arbitrary Circles (which you've trashed), it iterates through the list of Circles and prints
each one.

Now you should have an application that might produce something like the following picture.
In this case, the user asked for 9 circles, which the program labeled 0 through 8. At this
point, you have completed this project. It will be extended in the final homework!
