Examples of java.awt.Polygon.addPoint()

java.awt.Polygon.addPoint()
Appends the specified coordinates to this Polygon.
If an operation that calculates the bounding box of this Polygon has already been performed, such as getBounds or contains, then this method updates the bounding box. @param x the specified X coordinate @param y the specified Y coordinate @see java.awt.Polygon#getBounds @see java.awt.Polygon#contains @since 1.0
