Probiers mal mit der Klasse java.text.SimpleDateFormat, da kannst du beim Erstellen ein Format angeben wie das Datum aussehen darf, in etwa so
SimpleDateFormat sdf = new SimpleDateFormat( „dd.MM.YYYY HH:mm:ss“ );
Date d = sdf.parse( „13.12.2000 11:11:11“ );
Kann auch mit Monaten als Bezeichnung („Nov“, „July“) und vielem mehr umgehen. Hier der Auszug aus der Doku der den Beschreibungsstring im Constructor dokumentiert:
Time Format Syntax:
To specify the time format use a time pattern string. In this pattern, all ASCII letters are reserved as pattern letters, which are defined as the following:
Symbol Meaning Presentation Example
G era designator (Text) AD
y year (Number) 1996
M month in year (Text & Number) July & 07
d day in month (Number) 10
h hour in am/pm (1~12) (Number) 12
H hour in day (0~23) (Number) 0
m minute in hour (Number) 30
s second in minute (Number) 55
S millisecond (Number) 978
E day in week (Text) Tuesday
D day in year (Number) 189
F day of week in month (Number) 2 (2nd Wed in July)
w week in year (Number) 27
W week in month (Number) 2
a am/pm marker (Text) PM
k hour in day (1~24) (Number) 24
K hour in am/pm (0~11) (Number) 0
z time zone (Text) Pacific Standard Time
’ escape for text
‚‘ single quote ’
The count of pattern letters determine the format.
(Text): 4 or more pattern letters–use full form, > 1996.07.10 AD at 15:08:56 PDT
„EEE, MMM d, ''yy“ ->> Wed, July 10, ‚96
„h:mm a“ ->> 12:08 PM
"hh ‚o‘‘’‚clock‘ a, zzzz" ->> 12 o’clock PM, Pacific Daylight Time
„K:mm a, z“ ->> 0:00 PM, PST
„yyyyy.MMMMM.dd GGG hh:mm aaa“ ->> 1996.July.10 AD 12:08 PM
Code Sample:
SimpleTimeZone pdt = new SimpleTimeZone(-8 * 60 * 60 * 1000, „PST“);
pdt.setStartRule(DateFields.APRIL, 1, DateFields.SUNDAY, 2*60*60*1000);
pdt.setEndRule(DateFields.OCTOBER, -1, DateFields.SUNDAY, 2*60*60*1000);
// Format the current time.
SimpleDateFormat formatter
= new SimpleDateFormat („yyyy.mm.dd e ‚at‘ hh:mm:ss a zzz“);
Date currentTime_1 = new Date();
String dateString = formatter.format(currentTime_1);
// Parse the previous string back into a Date.
ParsePosition pos = new ParsePosition(0);
Date currentTime_2 = formatter.parse(dateString, pos);
In the example, the time value currentTime_2 obtained from parsing will be equal to currentTime_1. However, they may not be equal if the am/pm marker ‚a‘ is left out from the format pattern while the „hour in am/pm“ pattern symbol is used. This information loss can happen when formatting the time in PM.
For time zones that have no names, use strings GMT+hours:minutes or GMT-hours:minutes.
The calendar defines what is the first day of the week, the first week of the year, whether hours are zero based or not (0 vs 12 or 24), and the time zone. There is one common decimal format to handle all the numbers; the digit count is handled programmatically according to the pattern.
