本文實(shí)例講述了Java中計(jì)算時(shí)間差的方法。分享給大家供大家參考。具體如下：
假設(shè)現(xiàn)在是2004-03-26 13：31：40
過(guò)去是：2004-01-02 11：30：24
要獲得兩個(gè)日期差，差的形式為：XX天XX小時(shí)XX分XX秒

DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");try{ Date d1 = df.parse("2004-03-26 13:31:40"); Date d2 = df.parse("2004-01-02 11:30:24"); long diff = d1.getTime() - d2.getTime(); long days = diff / (1000 * 60 * 60 * 24);}catch (Exception e){} |

希望本文所述對(duì)大家的java程序設(shè)計(jì)有所幫助。
