    public class BullseyeApplet extends JApplet

    	private void drawCircle(Graphics g, int centerX, int centerY, int diameter, Color color)

    		drawCircle(g, 100, 100, 150, Color.BLUE);
    		drawCircle(g, 100, 100, 125, Color.GREEN);
    		drawCircle(g, 100, 100, 100, Color.BLUE);
    		drawCircle(g, 100, 100, 75, Color.GREEN);
    		drawCircle(g, 100, 100, 50, Color.BLUE);
    	}
    }

    C:\Users\Chico\Documents\BullseyeApplet.java:13: error: cannot find symbol
    		g.fillCircle(centerX - diameter/2,centerY - diameter/2,diameter,diameter);
    		 ^
      symbol:   method fillCircle(int,int,int,int)
      location: variable g of type Graphics

    That's my code, for some reason it recognizes g.setColor(color);, but it won't recognize any other instance of g. I don't understand why!

    You have several uses of g outside the scope where g was declared.

    Ah yes, ignore that, I fixed that part, was more focused on why g.fillCircle was not being recognized. I'll edit the post code real quick!

    If it says it can't find fillCircle(), maybe there is no such method for Graphics. Do you, perhaps, need to use fillOval()?


    Cheers!

    *Cough*
    Look, the real question here is not who meant to use what, the real question is, how fast can we ignore this and pretend I DIDN'T use circle.

    EDIT:
    Hey I did the frame version without error, yay I'm getting better at graphics! I'm terrible with it right now T_T
