I want the date format as dd-MMM-yyyy. My code is:
String v_date_str="Sun Mar 06 11:28:16 IST 2011";
DateFormat formatter;
formatter = new SimpleDateFormat("dd-MMM-yyyy");
Date date_temp=null;
try {
date_temp = (Date) formatter.parse(v_date_str);
} catch (ParseException ex) {
Logger.getLogger(Attendance_Calculation.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("output: "+date_temp);
But, I got the error as:
The log message is null.

So just remove those characters from string by using day. split(":"); String day1=day[1]; just give this day1 string in parse(); Now the updated code like as below..
Class ParseExceptionSignals that an error has been reached unexpectedly while parsing. See Also: Exception , Format , FieldPosition , Serialized Form.
SimpleDateFormat is a concrete class for formatting and parsing dates in a locale-sensitive manner. It allows for formatting (date -> text), parsing (text -> date), and normalization. SimpleDateFormat allows you to start by choosing any user-defined patterns for date-time formatting.
You should change your code to:
String v_date_str="Sun Mar 06 11:28:16 IST 2011";
DateFormat formatter;
formatter = new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Date date_temp=null;
try {
date_temp = (Date) formatter.parse(v_date_str);
} catch (ParseException ex) {
Logger.getLogger(Attendance_Calculation.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println("output: "+date_temp);
You are using the wrong date format for parsing the date.
