The last X and Y coordinates for the circle’s center are used to draw the single, solitary circle. You need to add ten thousand … Read more

Preface: Given your “console application” doesn’t involve forking any processes or performing any “actual” I/O, you may want to redesign your application to use the TextField and TextArea directly, or at least more directly than you’re currently trying to do.
