package a;

public enum HelloWorld  {
    SMALL,MEDIUM,LARGE,SUPERSTAR;


    public static void main(String[] args) {
        EnumMap<HelloWorld,String> cakes=new EnumMap<HelloWorld, String>(HelloWorld.class) ;
        cakes.put(SMALL,"太小了吧");
        cakes.put(SUPERSTAR,"超级大，无人能比");
        System.out.println(cakes.size());
        System.out.println( cakes.values());
        System.out.println( cakes.keySet());
        System.out.println(cakes.get(LARGE));
        System.out.println(cakes.containsKey(MEDIUM));
        System.out.println(cakes.containsValue("超级大，无人能比"));
