java8-Enum

Enum是所有enum類型的父類。注意，Enum類型不能被序列化，它是一個抽象類。

public static void main(String[] args) throws NoSuchFieldException, SecurityException
    {
        TT t = Enum.valueOf(TT.class, "TEST");
        System.out.println(t);
        System.out.println(Object.class.isAssignableFrom(Enum.class));
        System.out.println(Enum.class.isAssignableFrom(TT.class));
    }

    static enum TT implements Serializable
    {
        TEST("zzz", 1);
        private String name;
        private int i;

        private TT(String name, int i)
        {
            this.name = name;
            this.i = i;
        }

    }
