Experiment G1.3, Step 1. Since Java draws both circles in exactly the same place, we might expect one of two things to happen: (1) the two colors could blend, yielding a third color or (2) the second color could obscure the underlying color. By default, Java uses opaque paints, so the second option occurs. That is, only the second circle is visible.
Experiment G1.3, Step 2. Although intuition would suggest that the first circle (red, in our example) would not appear, the differences between drawing and filling lead to a situation in which small pieces of blue should be visible.
