Hi guys,

Im struggling with figuring out a way to make the following code work:

public class traffic_light implements Runnable {
    
    
     enum trafficState { Stop, PrepareToGo, Go, PrepareToStop }
    public String name = "";
   
    public traffic_light(String name)
     
    {
        this.name = name;
    }
       
    public trafficState nowState;
   
    public void run () {
       
    nowState = trafficState.Go;
    
     while (true)
    
        {
            timer(1000);
         
            switch (nowState)
           
            {             
                case Stop:
                    nowState = trafficState.PrepareToGo;
                    break;
            
                case PrepareToGo:
                    nowState = trafficState.Go;
                    break;
            
                case Go:
                    nowState = trafficState.PrepareToStop;
                    break;
            
                case PrepareToStop:  
                    nowState = trafficState.Stop;
                    break;
               
            } // End switch
           
            this.printOut(nowState);
         
        } // End while.
           
    } //End Run
   
    public void printOut (trafficState state) {
       
        System.out.println("The " + name + " traffic lights say " + state);
       
    }
       
    public static void timer (int delay) {
   try {
     Thread.sleep(delay); //timer sleeps for 1 second
   } catch (InterruptedException exception) {
     //Does nothing
       }
     } // End timer.
 
     public static void main (String args[]) {
   traffic_light trafficLight = new traffic_light("normal");
   trafficLight.run();
   
   } // End main.

} // End TrafficLight

Im just getting 2 errors, both concerning this line:
enum trafficState { Stop, PrepareToGo, Go, PrepareToStop } stating that
there should be an = before the { and ; expected at the end.  Im really not
sure how to fix it.  Can anyone give any pointers?

Thanks in advance,

Matt
