Examples of java.awt.Graphics.drawPolygon()

java.awt.Graphics.drawPolygon()
Draws a closed polygon defined by arrays of x and y coordinates. Each pair of (x, y) coordinates defines a point.
This method draws the polygon defined by nPoint line segments, where the first nPoint - 1 line segments are line segments from (xPoints[i - 1], yPoints[i - 1]) to (xPoints[i], yPoints[i]), for 1 ≤ i ≤ nPoints. The figure is automatically closed by drawing a line connecting the final point to the first point, if those points are different. @param xPoints a an array of x coordinates. @param yPoints a an array of y coordinates. @param nPoints a the total number of points. @see java.awt.Graphics#fillPolygon @see java.awt.Graphics#drawPolyline
