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;}

public void getDate(String unixDate) { SimpleDateFormat fm1 = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss"); SimpleDateFormat fm2 = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); long unixLong = 0; String date = ""; try { unixLong = Long.parseLong(unixDate) * 1000; } catch(Exception ex) { System.out.println("String转换Long错误，请确认数据可以转换！"); } try { date = fm1.format(unixLong); date = fm2.format(new Date(date)); } catch(Exception ex) { System.out.println("String转换Date错误，请确认数据可以转换！"); } System.out.println(date);}

System.currentTimeMillis();
