Hi all

at last fixed my self, to fill the different colors to petals in
Flower.java, just I replaced petal method with this code.

private void petal( double radius, double degrees ){

for ( double i = radius; i > 0 ; i-- ) {
setPenWidth( (int)(degrees /100) );
arcRight( i, degrees );
right( 180 - degrees );
arcRight( i, degrees );
right( 180 - degrees );
}
}
