As it happens, I developed a simple static method to do exactly what you
want a few years back. Here's the code:

----------------------------------------------------------------------------
-----------------
/**
* Method getMonthEnglish() returns the full English month name
corresponding to
* a 0-based month number.
*
* @since 2003
*
* @return the English month name for a given 0-based month number
*/

static public String getMonthEnglish(int monthNumber) {

String[] MONTH_NAMES_ENGLISH = { "January", "February",
"March", "April", "May", "June", "July", "August", "September",
"October", "November", "December" };

return MONTH_NAMES_ENGLISH[monthNumber];
}

----------------------------------------------------------------------------
-----------------

To invoke this method, just imitate this example:

int monthNumber = 0;
String monthName = getMonthEnglish(monthNumber);
System.out.println("Month number = " + monthNumber + "; Month name = " +
monthName);

All of this assumes that you are only concerned with English month names;
better code would look up the month name based on Locale so that month 0
would be 'janvier' in French, 'januar' in German, etc.
