JSP中如何比较时间

比较两个时间的先后顺序：

import java.text.*;import java.util.*;public class TestDate {    public static void main(String[] args) {        String dStr = "2006.09.20-08.23.21";        Date d = null;        SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd-HH.mm.ss");        try {            d = sdf.parse(dStr);        } catch (ParseException e) {            System.out.println(e.getMessage());        }        System.out.println(d);        System.out.println(d.getTime());    }}

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Date date1 = sdf.parse("2006-09-20 09:10:00");Date date2 = sdf.parse("2006-09-20 08:05:40");

System.out.println(date1);System.out.println(date2);

boolean isAfter = date1.after(date2
