Formatting a Date Using a Custom Format
A pattern of special characters is used to specify the format of the
date. This example demonstrates some of the characters. For a
complete listing, see the javadoc documentation for the
SimpleDateFormat class.
Note: This example formats dates using the default locale
(which, in the author's case, is Locale.ENGLISH). If the example is
run in a different locale, the text (e.g., month names) will not be
the same.
Format formatter;
// The year
formatter = new SimpleDateFormat("yy"); // 02
formatter = new SimpleDateFormat("yyyy"); // 2002
// The month
formatter = new SimpleDateFormat("M"); // 1
formatter = new SimpleDateFormat("MM"); // 01
formatter = new SimpleDateFormat("MMM"); // Jan
formatter = new SimpleDateFormat("MMMM"); // January
// The day
formatter = new SimpleDateFormat("d"); // 9
formatter = new SimpleDateFormat("dd"); // 09
// The day in week
formatter = new SimpleDateFormat("E"); // Wed
formatter = new SimpleDateFormat("EEEE"); // Wednesday
// Get today's date
Date date = new Date();
// Some examples
formatter = new SimpleDateFormat("MM/dd/yy");
String s = formatter.format(date);
// 01/09/02
formatter = new SimpleDateFormat("dd-MMM-yy");
s = formatter.format(date);
// 29-Jan-02
// Examples with date and time; see also
// Formatting the Time Using a Custom Format
formatter = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss");
s = formatter.format(date);
// 2002.01.29.08.36.33
formatter = new SimpleDateFormat("E, dd MMM yyyy HH:mm:ss Z");
s = formatter.format(date);
// Tue, 09 Jan 2002 22:14:02 -0500
