Simple Inheritance

Posted by Kishori Sharan on January 03, 2001 at 9:24 AM

The argument to paint method can take an object of Graphics class or its subclass. In fact , at run time an object of class WGraphics is passed to paint method. The class hierarchy is as follows. It's simply inheritance!!!

public java.lang.Object
public abstract java.awt.Graphics
public abstract java.awt.Graphics2D
public abstract sun.java2d.SunGraphics2D
public sun.awt.windows.WGraphics extends SunGraphics2D implements PixelDrawPipe, PixelFillPipe, TranslateablePipe, SimpleRenderPipe, TextPipe, DeviceClipping
