    enum Seasons {
        WINTER, SPRING, SUMMER, FALL;
    }

    public static boolean needJacket(Seasons s){
        return s == Seasons.WINTER || s == Seasons.FALL;
    }

    public static void main(String[] args) {
        System.out.println("It is: " + Seasons.WINTER.name());
        if(needJacket(Seasons.WINTER)){
            System.out.println("I should wear a jacket");
        }
