Homework: Java calculator dealing with dates -- Is my array correct?

I'm working on a Java assignment, where we take a date and do some calculations on it in various ways. Right now I'm working on a piece that will use my Array. Basically it's a list of the months by day. 0 for January 1st, 31 for Feburary 1, etc...

Does my array look correct based on these values?

Here's my array:

  private static int[] cumulDays = {0,31,59,90,120,151,181,212,243,273,304,334};

Java Assignment Doc for reference: http://www.cs.colostate.edu/~cs161/assignments/PA2/doc/MyUTC.html#cumulDays

cumulDays private static int[] cumulDays number of days from the beginning of the year to the beginning of a month (0 for Jan, 31 for Feb, ...). You will want to initi开发者_如何学编程alize this.

Your array values are correct. However, as the assignment Javadoc state, "you will want to initialize this"; you need to take into account leap years. However, since you basically don't have that many array possibilities, you could simply create two static arrays

private static int[] CUMUL_DAYS = {0,31,59,90,120,151,181,212,243,273,304,334};
private static int[] CUMUL_DAYS_LEAP = {0,31,60,91,121,152,182,213,244,274,305,335};

and depending on if the year is leap or not, return one of the static array

Yes, that is correct. His last value is 334 because the zero is given for January 1st (as zero days have passed at that point). You may consider entering a cumulative entry of value 365 at 12 for December 31st, but it depends on how you are manipulating your date-data.

Depending on the specifications of your homework, it may be more beneficial to use Java's built in Date class.
