很多朋友都想知道怎么獲取java秒級時間戳？下面就一起來了解一下吧~

方法一：通過String.substring()方法將最后的三位去掉

/**?
?*?獲取精確到秒的時間戳?
?*?@return?
?*/??public?static?int?getSecondTimestamp(Date?date){??
????if?(null?==?date)?{??
????????return?0;??
????}??
????String?timestamp?=?String.valueOf(date.getTime());??
????int?length?=?timestamp.length();??
????if?(length?>?3)?{??
????????return?Integer.valueOf(timestamp.substring(0,length-3));??
????}?else?{??
????????return?0;??
????}??
}

方法二：通過整除將最后的三位去掉

/**?
?*?獲取精確到秒的時間戳?
?*?@param?date?
?*?@return?
?*/??public?static?int?getSecondTimestampTwo(Date?date){??
????if?(null?==?date)?{??
????????return?0;??
????}??
????String?timestamp?=?String.valueOf(date.getTime()/1000);??
????return?Integer.valueOf(timestamp);??
}
