Default case not working in a switch statement

Question

I get a run-time error when i input other flavor than the three listed in the code.
Any comments and suggestions are welcomed.
import java.util.Scanner;
public class EnumSwitchDemo
     enum Flavor {VANILLA, CHOCOLATE, STRAWBERRY};
     public static void main(String[] args)
          Flavor favorite = null;
          Scanner keyboard = new Scanner(System.in);
          System.out.println("What is your favorite flavor? ");
          String answer = keyboard.next();
          answer = answer.toUpperCase();
          favorite = Flavor.valueOf(answer);          
          switch(favorite)
               case VANILLA:
                    System.out.println("Classic");
                    break;
               case CHOCOLATE:
                    System.out.println("Rich");
                    break;
               case STRAWBERRY:
                    System.out.println("Tasty");
                    break;
               default:
                    System.out.println("Sorry, Flavor unavailable");
                    break;
}

Yes, the static valueOf method of an Enum type throws an IllegalArgumentException, if the name is not defined, I think. So the problem is not the switch statement.
Btw, normally you don't need switch statements with enums, since you can define methods in enums.
