Problem:

The following lines of code draw the eyes of the snowman in the Snowman applet. The eyes seem centered on the face when drawn, but the first parame¬ters of each call are not equally offset from the midpoint. Explain.
page.fillOval (MID-10, TOP+10, 5, 5);
page.fillOval (MID+5, TOP+10, 5, 5);

Output:

Not Available

Solution:

The first parameter specifies the upperleft corner of the eyes, not the center of the eyes. The eyes are circles of diameter 5. Hence, the center of the first eye is –10 + 2.5 = -7.5 units to the left of MID, and the second eye is 5 + 2.5 = 7.5 units to the right of MID.
