很多朋友都想知道怎麼獲取java秒級時間戳?下面就一起來了解一下吧~
方法一:透過String.substring()方法將最後的三位去掉
/** * 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:透過整除將最後的三位去掉
/** * 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); }
