DateFormat class
In this chapter you will learn:
Create DateFormat to format date
DateFormat is an abstract class for date/time formatting.
It provides the ability to format and parse dates and
times.
The getDateInstance() method returns an instance of DateFormat
that can format date information.
It is available in these forms:
static final DateFormat getDateInstance( )
static final DateFormat getDateInstance(int style)
static final DateFormat getDateInstance(int style, Locale locale)
The argument style is one of the following values: DEFAULT, SHORT,
MEDIUM, LONG, or FULL.
These are int constants defined by DateFormat.
The argument locale is one of the static references defined by Locale.
If the style and/or locale is not specified, defaults are used.
format() method has several overloaded forms, one of which is shown here:
final String format(Date d)
The argument is a Date object that is to be displayed.
The method returns a string containing the formatted information.
import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;
/*from j av a 2 s . com*/
public class Main {
public static void main(String args[]) {
Date date = new Date();
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));
}
}
