Long和Date数据类型之间相互转换代码

static final SimpleDateFormat DATETIME_SEC_STR = new SimpleDateFormat("yyyyMMddHHmmss");

1.Date转Long

Long currStartTime = Long.valueOf(DATETIME_SEC_STR.format(new Date()));
System.err.println("LONG1: " + currStartTime);

 

2.Long转Date

Date d1 = DATETIME_SEC_STR.parse(String.valueOf(20140811140810l));
System.err.println("DATE2: " + d1);
