unexpected result of parsing date
Submitted by essam on Sat, 2006-10-07 08:23.
salmo 3lykom i tried to parse adate in format -->dd/mm/yy
but i get an unexpected result can you tell me why?
SimpleDateFormat df=new SimpleDateFormat("dd/MM/yy");
df.parse("02/10/06")
System.out.print(df.parse("02/10/06"));
//the result will be
Mon Oct 02 00:00:00 GMT+04:00 2006
while i expect
02/10/06
what's the problem
Parse converts a string to a Date object
Al salamo alikom wa rahmat allah wa barakatoh
The parse method of class SimpleDateFormat takes a String as input and returns a Date object represents the date in the input String
ie df.parse("1/1/2006"); will return a java.util.Date object with the time from 1/1/1970 to 1/1/2006 12:00:00:00
so when you parsed "02/10/06" you've got a java.util.Date object and when you passed that object to System.out.println(...), the Date.toString() method was called and that method returns the default representation for the Date object which will be "Mon Oct 02 00:00:00 GMT+04:00 2006"
and to get the result that you want, you need to use the format method on the Date object you just parsed [ie, System.out.println(df.format(df.parse("02/10/06")))], that will print "02/10/06" on the screen.

the SimpleDateFormat class is used to convert String representations for Date/Time to java.util.Date objects and converting the java.util.Date objects to a String representation for the Date/Time stored in the Date object, and the java.util.Date class is used to store the time since 1/1/1970 12:00:00 until a specified time, it has nothing to do with the String representation for the stored date.
so If you want to convert the String "1/1/2006 01:30:00" to a java.util.Date object, you will use SimpleDateFormat.parse("..."), thing method will return a java.util.Date object contains the time from 1/1/1970 until 1/1/2006 01:30:00
java.util.Date t = simpleDateFormatObject.parse("1/1/2006 01:30:00");
and if you have a java.util.Date object contains the time from 1/1/1970 util 1/1/2006 and you want to convert it to a String contains the value "1 - 1 - 70", you will use the method SimpleDateFormat.format(dateObject).
String str = simpleDateFormatObject.format(theDateObject); // str will be "1 - 1 - 70" with the specified pattern
NOTE: the java.util.Date objects store the Date/Time in the form of Ticks, units smaller that mil.Secs.
back to the SimpleDateFormat class documentation in the javadocs to get more information about parsing and formatting dates and times.

Humm, here is a solution
al salamo alikom wa rahmat allah wa barakatoh
Why do you want to print the Date object on the screen without using SimpleDateFormat to convert it to a String ?
anyway, to do the required, make another class "MyDate" extends java.util.Date
and overide the method "toString()" and make that method returns the String represenation you want.

actually i dont need to print the date on the screen as astring
but i need to read the string 12/02/06
and put in in adate
with the same format
Date date=new Date("12/02/06");
thank you man
thank you man
today i found aolution
DateFormat dateFormat = new SimpleDateFormat("dd/MM/yy");
java.util.Date issue = dateFormat.parse(request.getParameter("issuedate").toString());
