Alternative if statement & toString

I had to write a program for class to check and validate a date is correct. Check if year is between a certain range, check to make sure month is between 1 & 12. Then verify that there is the correct number of days in each month, along with check to see if it's a leap year or not for feb.

The if statements I wrote work but is there a way to clean this up a bit more or an alternative?

Then last part would be the toString. I still havent heard that if the date displays if it needs to be MM/DD/YYYY, or if it can be M/D/YYYY ex 02/02/2000 or 2/2/2000.

I know that using StringBuffer i can append, but how would I add the 0 before the day or month. I'm still tinkering with it, but not seeing any other solutions. I'm just going to assume that the date format needs to be 02/02/2000

Thanks in advance.

Look into DateFormat and SimpleDateFormat. You can use a DateFormat to parse a string into a Date object. It will throw an exception if the string is not valid. See the setLenient method, too.


A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
