Thread: java comp sci help

Can you explain what it you mean by "sort the circles based on color" and say what problems you are having doing it?

Please edit your post and wrap your code with code tags:

to get highlighting and preserve formatting.

having issues with the get color method and drawing the circles across the screen.

Please explain what the issues are.
Post any doc you want associated with the problem on the thread without requiring a download.

One problem I see is the creating of an object from inside the paint() method. Objects should be created outside the paint() method. Their methods can be called from inside paint().

ok I am very sorry I attached the wrong word document. I have figured out my problems with the sorting on my own today but I just would to know how to get those circles to display across the screen.

The code tags should go around the code, not at the end of the code. The code should be between the code tags at the place that says: <YOUR CODE HERE>

One problem I see is the creating of the Circle object from inside the paint() method. Objects should be created outside the paint() method. Their methods can be called from inside paint().

how to get those circles to display across the screen.

Change the y values of where the circles are drawn to have them display across the screen.


The code needs formatting. Nested statements should be indented. All statements should NOT start in the first column.
