是否允许在java枚举构造函数中使用varargs？

Question

enum MyEnum {
     A( 1, 2, 3, 4),
     B(1, 2),
     C(4, 5, 8, 8, 9);

    private MyEnum( int firstInt, int... otherInts ) {
     // do something with arguments, perhaps initialize a List
    }
}

Are there any problems with this? Any reasons not to do it?

Answer 1

Sure, this is perfectly legal. No reason not to do it if your program requires it.

Answer 2

it does work. You should try to

private MyEnum(int... Ints )

With enums you need to make sure that you access them in a manner the initializes them. A lot of the time an access is all that is needed

MyEnum bob = MyEnum.A;
