枚举？构造器？面试Demo

打印的结果是？ 

enum AccountType
{
    SAVING, FIXED, CURRENT;
    private AccountType()
    {
        System.out.println("It is a account type");
    }
}
class EnumOne
{
    public static void main(String[]args)
    {
        System.out.println(AccountType.FIXED);
    }
}

 枚举类有三个实例，故调用三次构造方法，打印三次It is a account type
