enum - simple example

    enum Apple {
       RED("drink"), GREEN("cook");

       private final String color;

       Apple(String colorNew) {
          this.color = colorNew;
       }

       String getColor() {
          return color;
       }
    }

    public class EnumTest3 {

       public static void main(String[] args) {

          for (Apple a : Apple.values()) {
              //inside println we can type "a.name()" to get name
              //or simply type "a" as follows:
             System.out.println(a +" apples are used to "+ a.getColor());
          }
       }
    }
