Answer:
When a star is too small, don't draw it.
Small Stars
This is a somewhat hard thought, and I suggest that you get out pencil and paper and draw some stars attached to stars attached to stars. After a while it is clear that you want to stop drawing when the stars are too small to draw. Our applet is no different:
private void drawStar( int x, int y, int size )
{
int endX, endY ;
if ( size <= 2 ) return; // base case
// Six lines radiating from (x,y)
for ( int i = 0; i<6; i++ )
{
endX = x + (int)(size*Math.cos( (2*Math.PI/6)*i ));
endY = y - (int)(size*Math.sin( (2*Math.PI/6)*i ));
graph.drawLine( x, y, endX, endY );
drawStar( endX, endY, size/3 );
}
}
I picked the value "2" for the base case. Smaller values result in cluttered snowflakes.

In this code, if the if statement followed the
for statement, would everything be OK?
