It should be that adding the code below to an applet code ...this will 
be  also an application ...but if java.awt.Component is used will have
the error >>>  width is not public in java.awt.Component; cannot be 
accessed from outside package .


public static void main( String args[] )
    {
       int width, height;

       if ( args.length != 2 ) {  // no command-line arguments
          width = 300;
          height = 200;
       }
       else {
          width = Integer.parseInt( args[ 0 ] );
          height = Integer.parseInt( args[ 1 ] );
       }

       // create window in which applet will execute
       JFrame applicationWindow =
          new JFrame( "An applet running as an application" );

       applicationWindow.addWindowListener(
          new WindowAdapter() {
             public void windowClosing( WindowEvent e )
             {
                System.exit( 0 );
             }
          }
       );

       // create one applet instance
       DrawShapes appletObject = new DrawShapes();
       appletObject.setWidth( width );
       appletObject.setHeight( height );

       // call applet's init and start methods
       appletObject.init();
       appletObject.start();

       // attach applet to center of window
       applicationWindow.getContentPane().add( appletObject );

       // set the window's size
       applicationWindow.setSize( width, height );

       // showing the window causes all GUI components
       // attached to the window to be painted
       applicationWindow.show();
    }
