Graphics methods

The Graphics drawPolygon method can be used to draw outline polygons, and the Graphics fillPolygon method can be used to draw filled polygons. 

java.awt.Graphics

void drawPolygon (int[] XArray, int[] YArray, int N)

void fillPolygon (int[] XArray, int[] YArray, int N)

XArray

Array of the horizontal locations of the vertices of the polygon, in pixels.

YArray

Array of the vertical locations of the vertices of the polygon, in pixels.

N

Number of points.
