java 计算两个日期之间的差
简介:需求是根据登录时间和当前时间是否超过24小时,来进行业务操作, 因此需要计算时间之差来进行判断。
代码如下:
public static String getDateDiscrepency(Date endDate, Date nowDate) { long nd = 1000 * 24 * 60 * 60; long nh = 1000 * 60 * 60; long nm = 1000 * 60; // long ns = 1000; // 获得两个时间的毫秒时间差异 long diff = endDate.getTime() - nowDate.getTime(); // 计算差多少天 long day = diff / nd; // 计算差多少小时 long hour = diff % nd / nh; // 计算差多少分钟 long min = diff % nd % nh / nm; // 计算差多少秒//输出结果 // long sec = diff % nd % nh % nm / ns; return day + "天" + hour + "小时" + min + "分钟"; }
