Java Date Format

Below examples explains how to do date format using SimpleDateFormat and how to convert string to date in java.

SimpleDateFormat Example

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

public class DateFormatExample {

    public static void main(String args[]) {

        Date date = new Date();

        String DATE_FORMAT = "MM:dd:yyyy";
        // or
        // String DATE_FORMAT = "MM/dd/yyyy";

        SimpleDateFormat simDateFormat = new SimpleDateFormat(DATE_FORMAT);

        System.out.println("Today is " + simDateFormat.format(date));

        // or If you want display time with AM/PM

        String TIME_FORMAT = "HH:mm:ss a";

        SimpleDateFormat timeFormat = new SimpleDateFormat(TIME_FORMAT);

        System.out.println("Now time is " + timeFormat.format(date));

        // Today date and Time

        System.out.println("Date and time is " + simDateFormat.format(date)
                + " " + timeFormat.format(date));
        }

}

Convert String to Date

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

public class StrToDate {
    public static void main(String[] args) {
        String stri = "18/12/2009";

        DateFormat simDateForm = new SimpleDateFormat("dd/MM/yyyy");
        Date dstr;
        try {
            dstr = (Date) simDateForm.parse(stri);
            System.out.println("Date is" + dstr);

        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}
