        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.SHORT,

                DateFormat.SHORT);

        String strDate = dateFormat.format(date);

        System.out.println("SHORT format = " + strDate);

        dateFormat = DateFormat.getDateTimeInstance(DateFormat.MEDIUM,

                DateFormat.MEDIUM);

        strDate = dateFormat.format(date);

        System.out.println("MEDIUM format = " + strDate);

        dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG,

                DateFormat.LONG);

        strDate = dateFormat.format(date);

        System.out.println("LONG format = " + strDate);

    }

}

Output:

date = Mon Dec 31 09:54:22 IST 2018

SHORT format = 12/31/18 9:54 AM

MEDIUM format = Dec 31, 2018 9:54:22 AM

LONG format = December 31, 2018 9:54:22 AM IST
