For example, if the regex doesn't match the result is null:

If it does match, we get the matching string back:
assert "10292" == "New York, NY 10292-0098".find(/\d{5}/)
If we have capture groups in our expression, we still get back the full match

For example, if the regex doesn't match, the result is null:
assert null == "New York, NY".find(~/\d{5}/) { match -> return "-$match-"}
If it does match and we don't have any capture groups in our regex, there is a single parameter on the closure that the match gets passed to:
assert "-10292-" == "New York, NY 10292-0098".find(~/\d{5}/) { match -> return "-$match-"}
If we have capture groups in our expression, our closure has one parameter for the match, followed by one for each of the capture groups:

If we have capture groups in our expression, and our closure has one parameter, the closure will be passed an array with the first element corresponding to the whole match, followed by an element for each of the capture groups:
assert "10292" == "New York, NY 10292-0098".find(~/(\d{5})-?(\d{4})/) { match, zip, plusFour -> assert array[0] == "10292-0098" assert array[1] == "10292" assert array[2] == "0098" return array[1] }
If a capture group is optional, and doesn't match, then the corresponding value for that capture group passed to the closure will be null as illustrated here:
assert "2339999" == "adsf 233-9999 adsf".find(~/(\d{3})?-?(\d{3})-(\d{4})/) { match, areaCode, exchange, stationNumber -> assert "233-9999" == match assert null == areaCode assert "233" == exchange assert "9999" == stationNumber return "$exchange$stationNumber" }

Create a String representation of this date according to the given format pattern.
For example, if the system timezone is GMT,
new Date(0).format('MM/dd/yy')
would return the string
"01/01/70"
. See documentation for SimpleDateFormat
for format pattern use.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).

public static java.lang.String getDateString(java.util.Date self)
Return a string representation of the 'day' portion of this date
according to the locale-specific DateFormat.SHORT
default format.

public static java.lang.String getDateTimeString(java.util.Date self)
Return a string representation of the date and time time portion of
this Date instance, according to the locale-specific format used by
DateFormat
. This method uses the DateFormat.SHORT
preset for the day portion and DateFormat.MEDIUM
for the time
portion of the output string.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).

public static java.lang.String format(java.util.Calendar self, java.lang.String pattern)
Shortcut for SimpleDateFormat
to output a String representation
of this calendar instance. This method respects the Calendar's assigned
TimeZone
, whereas calling cal.time.format('HH:mm:ss')
would use the system timezone.
Note that Calendar equivalents of date.getDateString()
and variants do not exist because those methods are Locale-dependent.
Although a Calendar may be assigned a Locale
, that information is
lost and therefore cannot be used to control the default date/time formats
provided by these methods. Instead, the system Locale would always be
used. The alternative is to simply call
DateFormat.getDateInstance(int, Locale)
and pass the same Locale
that was used for the Calendar.
