Private members in Enum Java [duplicate]

Question

public class Test {

    public static enum MyEnum {
        valueA(1),valueb(2),valuec(3),valued(4);
        private int i;
        private Object o;

        private MyEnum(int number) {
             i = number;
        }

        public void set(Object o) {
            this.o = o;
        }

        public Object get() {
            return o;
        }


     } 

    public static void main(String[] args) {
        System.out.println(MyEnum.valueA.i); // private
    }
}

output: 1

Why 1 is shown if it a private member in enum?

Answer 1

Outer classes have full access to the member variables of their inner classes, therefore i is visible in the Test class.

In contrast, if MyEnum was external to the Test class, the compiler would complain about the visibility of i,
