public class styledemo {
   public static void main(string[] args) {
      date now = new date();

      dateformat df = dateformat.getdateinstance();
      dateformat df1 = dateformat.getdateinstance(dateformat.short);
      dateformat df2 = dateformat.getdateinstance(dateformat.medium);
      dateformat df3 = dateformat.getdateinstance(dateformat.long);
      dateformat df4 = dateformat.getdateinstance(dateformat.full);
      string s = df.format(now);
      string s1 = df1.format(now);
      string s2 = df2.format(now);
      string s3 = df3.format(now);
      string s4 = df4.format(now);

      system.out.println("(default) today is " + s);
      system.out.println("(short) today is " + s1);
      system.out.println("(medium) today is " + s2);
      system.out.println("(long) today is " + s3);
      system.out.println("(full) today is " + s4);
   }
}

that program output the following:

(default) today is nov 8, 2000
(short) today is 11/8/00
(medium) today is nov 8, 2000
(long) today is november 8, 2000
(full) today is wednesday, november 8, 2000
