查找两个时间戳之间的时间间隔

Question

我有两个时间戳：

Timestamp loggedintime=rs.getTimestamp("LOGIN_TIME");
Timestamp loggedouttime=rs.getTimestamp("LOGOUT_TIME");

现在，我想要做的是找到这两个时间戳之间的间隔，如15分钟或1小时10分钟等。

但我不知道如何做到这一点。所以请帮助我

Answer 1

你走了，

Timestamp loggedintime=rs.getTimestamp("LOGIN_TIME");
Timestamp loggedouttime=rs.getTimestamp("LOGOUT_TIME");
long interval = loggedouttime.getTime() - loggedintime.getTime();
//total hours
long hours = interval / (60 * 60 * 1000);
//time period that should be represented in minutes
long minutes = (interval % (60 * 60 * 1000)) / (60 * 1000);
//time period that should be represented in seconds
long seconds = (interval % (60 * 1000)) / 1000;
System.out.println(hours + " hours " + minutes + " min " + seconds + " sec");

注意：请注意间隔时间不准确，因为不考虑小于一秒（<1000）的毫秒

Answer 2

您可以使用TimeStamp类的getTime()方法。

试试这个

long diff = loggedouttime.getTime() - loggedintime.getTime();

Answer 3

long login=System.currentTimeMillis();
.
.
.
long logout=System.currentTimeMillis();

long difInSeconds=(logout-login)/1000;

long hours=difInSeconds/3600;
long minutes=difInSeconds%3600;
long seconds=difInSeconds-(hours*3600+minutes*60);
