java中有關日期的顯示問題

import Java.util.*;

import Java.text.*;

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
