java时间相减，得到天数

public static  void main(String args[]){SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");try {Date date1  = sdf.parse("2010-02-01 00:00:00");Date date2= sdf.parse("2010-02-15 00:00:00");long day = (date1.getTime()-date2.getTime())/(24*60*60*1000)>0 ? (date1.getTime()-date2.getTime())/(24*60*60*1000):(date2.getTime()-date1.getTime())/(24*60*60*1000);    System.out.println(day);} catch (ParseException e) {// TODO Auto-generated catch blocke.printStackTrace();}}
