BasicStroke Example – Draw Dashed Line in Applet Window in Java

In the Following example DashedLinesApplet shows with Basic Stroke how to Draw Dashed Line in Applet and set foreground color of an Applet window using Graphics2D class and setPaint(),setStroke(), BasicStroke() method of Graphics class. The Syntax for BasicStroke(float width, int cap, int join, float miterlimit, float[] dash, float dash_phase) ; setStroke is an inteface defined in the java.awt package.
