日期的显示格式化

import java.util.*;
import java.text.*;
public class FormatDate {
public static void main(String[] args) {
    Date now = new Date();

    DateFormat defaultFormat = DateFormat.getDateInstance();
    DateFormat shortFormat = DateFormat.getDateInstance(DateFormat.SHORT);
    DateFormat mediumFormat = DateFormat.getDateInstance(DateFormat.MEDIUM);
    DateFormat longFormat = DateFormat.getDateInstance(DateFormat.LONG);
    DateFormat fullFormat = DateFormat.getDateInstance(DateFormat.FULL);
    String defaultDate = defaultFormat.format(now);
    String shortDate = shortFormat.format(now);
    String mediumDate = mediumFormat.format(now);
    String longDate = longFormat.format(now);
    String fullDate = fullFormat.format(now);

    System.out.println("(Default) Today :" + defaultDate);
    System.out.println("(SHORT) Today : " + shortDate);
    System.out.println("(MEDIUM) Today :" + mediumDate);
    System.out.println("(LONG) Today : " + longDate);
    System.out.println("(FULL) Today : " + fullDate);
}
}

运行结果为:
