How do you construct a circle with coordinates?
Graphing a circle anywhere on the coordinate plane is pretty easy when its equation appears in center-radius form. All you do is plot the center of the circle at (h, k), and then count out from the center r units in the four directions (up, down, left, right). Then, connect those four points with a nice, round circle.
How do I fill a circle with color in Java applet?

Can you draw with Java?
Java provides a ton of great tools for drawing lines and shapes. Through the Graphics or Graphics2D class, we can draw and fill a wide variety of items. When drawing shapes, you create a paint method that invokes the Graphics class. You can draw a line with drawLine and rectangles with drawRect.
What is paintComponent method in Java?
