Java实现的时间戳与date对象相互转换功能示例

public long getTimestamp() throws ParseException{ Date date1 = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss")  .parse("2009/12/11 00:00:00");  Date date2 = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss")  .parse("1970/01/01 08:00:00");  long l = date1.getTime() - date2.getTime() > 0 ? date1.getTime()  - date2.getTime() : date2.getTime() - date1.getTime();  long rand = (int)(Math.random()*1000);  return rand;}
