How to format a date in java?

Question

How can change this date format \"2011-09-07T00:00:00+02:00\" into the \"dd.MM.\" i.e \"07.09.\"

Thanks in advance!

Answer 1

Basically -

1. Create a date format object from the above string

2. Parse into a date object, and reformat however you prefer.

For example (I haven't tested this):

import java.text.DateFormat;
import java.util.Date;

public class DateFormatExample1 {

    public static void main(String[] args) {
        // Make a new Date object. It will be initialized to the current time.
        DateFormat dfm = new SimpleDateFormat("yyyy-mm-dd HH:mm:ss");
        Date d = dfm.parse("2011-09-07 00:00:00");

        // See what toString() returns
        System.out.println(" 1. " + d.toString());

        // Next, try the default DateFormat
        System.out.println(" 2. " + DateFormat.getInstance().format(d));

        // And the default time and date-time DateFormats
        System.out.println(" 3. " + DateFormat.getTimeInstance().format(d));
        System.out.println(" 4. " +
            DateFormat.getDateTimeInstance().format(d));

        // Next, try the short, medium and long variants of the
        // default time format
        System.out.println(" 5. " +
            DateFormat.getTimeInstance(DateFormat.SHORT).format(d));
        System.out.println(" 6. " +
            DateFormat.getTimeInstance(DateFormat.MEDIUM).format(d));
        System.out.println(" 7. " +
            DateFormat.getTimeInstance(DateFormat.LONG).format(d));

        // For the default date-time format, the length of both the
        // date and time elements can be specified. Here are some examples:
        System.out.println(" 8. " + DateFormat.getDateTimeInstance(
            DateFormat.SHORT, DateFormat.SHORT).format(d));
        System.out.println(" 9. " + DateFormat.getDateTimeInstance(
            DateFormat.MEDIUM, DateFormat.SHORT).format(d));
        System.out.println("10. " + DateFormat.getDateTimeInstance(
            DateFormat.LONG, DateFormat.LONG).format(d));
    }
}
