DateFormat df;

df = DateFormat.getDateInstance(DateFormat.SHORT, Locale.JAPAN);

System.out.println("Japan: " + df.format(date));

df = DateFormat.getDateInstance(DateFormat.MEDIUM, Locale.KOREA);

System.out.println("Korea: " + df.format(date));

df = DateFormat.getDateInstance(DateFormat.LONG, Locale.UK);

System.out.println("United Kingdom: " + df.format(date));

df = DateFormat.getDateInstance(DateFormat.FULL, Locale.US);
System.out.println("United States: " + df.format(date));
}
}

Sample output from this program is shown here:

Japan: 06/07/12

Korea: 2006. 7. 12

United Kingdom: 12 July 2006

United States: Wednesday, July 12, 2006

ThegetTimeInstance( )method returns an instance ofDateFormatthat can format time
information. It is available in these versions:

static final DateFormat getTimeInstance( )

static final DateFormat getTimeInstance(intstyle)

static final DateFormat getTimeInstance(intstyle, Localelocale)

The argumentstyleis one of the following values:DEFAULT,SHORT,MEDIUM,LONG,
orFULL. These areintconstants defined byDateFormat. They cause different details about
the time to be presented. The argumentlocaleis one of the static references defined byLocale.
If thestyleand/orlocaleis not specified, defaults are used.
The following listing illustrates how to format time information. It begins by creating a
Dateobject. This captures the current date and time information and then outputs the time
information by using different styles and locales.
