Determining the Number of Days in a Month</h3>
This example uses the <code>Calendar</code> class to determine the number of days
in the month of a particular year.
<pre>
// Create a calendar object of the desired month
Calendar cal = new GregorianCalendar(<font color="#0066ff"><i>1999</i></font>, Calendar.<font color="#0066ff"><i>FEBRUARY</i></font>, 1);
// Get the number of days in that month
int days = cal.getActualMaximum(Calendar.DAY_OF_MONTH); // 28
// Try month in a leap year
cal = new GregorianCalendar(<font color="#0066ff"><i>2000</i></font>, Calendar.<font color="#0066ff"><i>FEBRUARY</i></font>, 1);
days = cal.getActualMaximum(Calendar.DAY_OF_MONTH); // 29
