Exercise: Calendar

CalenderEntry

To store events in a calendar you should write a class CalenderEntry.

A CalenderEntry is defined by:

A description text:

• String text

The month of the year that the event occurs. For the sake of simplicity we define that every month has 28 days:

• int month

The day of the month that the event occurs:

• int day

A CalenderEntry is constructed with the text, month and day.

• CalenderEntry(String text, int month, int day)

A CalenderEntry can be checked if it is valid. It is valid if:

• a month has to be in range 1-12

• a day has to be in range 1-7

• boolean isValid()

It can be checked if two CalenderEntries are in the same month:

-boolean inSameMonth(CalenderEntry entry)

CalendarEntries can be compared to find out if the calendar entry is before another one. (Is the CalenderEntry before the one in the parameter)

• boolean isBefore(CalenderEntry entry)

It can be calculated how many days are left until the CalenderEntry from a given date (month, day).

• int daysLeft(int month, int day)
