Graphics g = this.getGraphi c s ( ) ;

int width = this.getWidth ( ) ;
int diff = width / 1 5 ;
int halfDiff = diff / 2 ;
int x = 0 ;
int y = 0 ;
// draw the red arc
g . s e tColor ( Color .RED) ;
g . f i l lArc (x , y , width , height , 0 , 1 8 0 ) ;
// draw the orange arc
width = width - diff ;
he i ght = height - d i f f ;
x = x + halfDiff ;
y = y + h alfDiff ;
g . s e tColor (new Color ( 255, 102, 0 ) ) ;
g . fill Ar c (x , y , width , height , 0 , 180 ) ;
// draw the yellow arc
width = width - diff ;
height = height - diff ;
x = x + halfDiff ;
y = y + halfDiff ;
g . setColor (Color .YELLOW) ;
g . fillArc (x , y , width , height , 0 , 180 ) ;
