Question

Implement an Enum in Java which enumerates the months of the year. Include in the enum the relevant position of the month in the calender i.e. Jan = 1, Feb = 2, etc and the number of days in the month i.e. Jan = 31, Feb = 28, etc. You do not need to provide support for leap years in the implementation. Provide a suitable toString() method to print information about the enumerated types.

    private final int days;

    private Month(int month, int days) {
        monthIndex = month;
        this.days = days;

    }

    @Override
    public String toString() {
        return name()+" = " + monthIndex + ", Days = " + days;
    }

    public static void main(String[] args) {

        Month jan = Month.Jan;
        System.out.println(jan);
        Month nov = Month.Nov;
        System.out.println(nov);
    }
}
