I cannot format a date.
dateFormat.format()
accepts a Date
as argument. So I created a new Date()
It says the below Date() method is deprecated, and I get the below exception while running.
exception:
Exception in thread "main" java.lang.IllegalArgumentException at
java.util.Date.parse(Date.java:598)
public class MyDate {
public static void main(String[] args) {
Date date = new Date("2012-02-16T00:00:00.000-0500");
SimpleDateFormat dateFormat = new SimpleDateFormat(
"dd-MMM-yyyy HH:mm:ss");
String stringDate = dateFormat.format(date);
System.out.println(stringDate); // how do I test this conversion??
}
}
My database has date of the format - 2012-02-16T00:00:00.000-0500 I need to convert it to string of the format : dd-MMM-yyyy HH:mm:ss
I'm using Java6

Thanks to @Andy Brown. In addition to what Andy Brown has answered, I'm posting the complete snippet
Complete Solution:
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class SampleDate {
public static void main(String[] args) throws ParseException {
DateFormat parseFormat = new SimpleDateFormat(
"yyyy-MM-dd'T'HH:mm:ss.SSSZ");
Date date = parseFormat.parse("2012-03-16T00:00:00.000-0500");
String strDate = parseFormat.format(date);
System.out.println(strDate);
// if you get date of type 'java.sql.Date' directly from database cursor like
//rs.getDate("created_date"), just pass it directly to format()
SimpleDateFormat dateFormat = new SimpleDateFormat(
"dd-MMM-yyyy HH:mm:ss");
String stringDate = dateFormat.format(date);
System.out.println(stringDate);
}
}
/*
Output:
2012-03-16T01:00:00.000-0400
16-Mar-2012 01:00:00
*/
you can also convert java.util.Date
to java.sql.Date
like this,
String dateString = "03-11-2012";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy");
java.util.Date date = dateFormat.parse(dateString);
java.sql.Date sqlDate = new Date(date.getTime());
// set the input param type as OracleTypes.DATE and pass the input param date as sqlDate

If you want to read in the date "2012-02-16T00:00:00.000-0500" you should probably use a SimpleDateFormat
to parse
it like so:
DateFormat parseFormat = new SimpleDateFormat(
"yyyy-MM-dd'T'HH:mm:ss.SSSZ");
Date date = parseFormat.parse("2012-02-16T00:00:00.000-0500");
Along with the rest of your code this writes:
16-Feb-2012 05:00:00
The parse format pattern letters are listed in the SimpleDateFormat
documentation. The T
is escaped with apostrophes.
This answer assumes Java 7, or you would be using the new date & time API from Java 8
