Case statements and Applets

Question

Basically what I am trying to do is create three Ovals (only mangaged to one but would appreciate some help if someone can tell me how to position ovals on a screen :=D) which when a single command is pressed the specified oval changes color, i.e. a traffic light system. I have done the following code but doesn't like the statement of - "case(butNext)". Can someone point me in the right direction :=). I tried something like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"... well something like that but was no good. Would appreciate it if someone could tell me how to position shapes using the graohic method. I know how to do it with command buttons, list boxes etc but its not the same with shapes :=(.
import java.awt.*;
import java.applet.*;
public class traffic extends Applet {
     Button butNext;
     Color red = Color.red;
     Color orange = Color.orange;
     Color green = Color.green;
     public void init() {
          butNext = new Button("Red");
          add(butNext);
     public void paint(Graphics g) {
          switch(butNext)
          case 0:
          g.setColor(red);
          g.fillOval(100,50,70,80);
          break;
          case 1:
          g.setColor(orange);
          g.fillOval(100,50,70,80);
          break;
          case 2:
          g.setColor(green);
          g.fillOval(100,50,70,80);
          break;
}Appreciate any responses. Thank You :=D

I have done the following code but doesn't
like the statement of - "case(butNext)". What do you mean "doesn't like" -- did you get an error message?
I'm guessing it won't compile because you're trying to switch on a Button.
I tried something
like "g.fillOval(100,50,70,90, BorderLayout.NORTH)"...no that doesn't make sense. You only use BorderLayout.NORTH when you're adding components to a BorderLayout layout manager. An oval is not a component and fillOval isn't adding a component and Graphics is not a Panel or layout manager.
Would appreciate it if someone could tell me how to position
shapes using the graohic method. I think the problem is that you're confusing shapes with components.
