Java : convert long to Timestamp

Question

I know, how to convert a Timestamp to a long, with the getTime() method.

Is there a method that convert a long to a TimeStamp?

Answer 1

This question is a bit old but for those arriving here scratching their heads because their Timestamp object does not include a (long) constructor, Firebase's com.google.firebase.Timestamp object include (Date date) constructor. and (long seconds, int nanoseconds) and Date does include a (long) constructor (which creates a date object based of number of seconds from epoch - same as java.sql.Timestamp

bottom line is your solution is simply either

Timestamp(new Date(longEpochTimeVar));

or

Timestamp(longEpochTimeVar,0);

0 stands for 0 nanoseconds so both option will produce the same result.
