Decoding Java Enums and Switch

Report a typo

Given the following code snippet, which statements are correct in terms of Enums in Java?

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY;

    public static void printDay(Day day) {
        switch(day) {
            case SUNDAY: System.out.println("It's Sunday!"); break;
            case MONDAY: System.out.println("It's Monday!"); break;
            // Other cases...
        }
    }
}

Select one or more options from the list

Enum's static method can be invoked without creating an instance of enum.

In the switch statement, after MONDAY case, 'default' statement should be added instead of other days cases.

In Java, it's correct to use the enum in the switch statement this way.

The Day enum can extend another class.

The `Day` enum can also be used to iterate over days of the week.
