Java 8 added a new API for working with dates and times. With Java 8 you can use

import java.time.Instant
...
long unixTimestamp = Instant.now().getEpochSecond();

Instant.now() returns an Instant that represents the current system time. With getEpochSecond() you get the epoch seconds (unix time) from the Instant.

Avoid the Date object creation w  System currentTimeMillis     A divide by 1000 gets you to Unix epoch   As mentioned in a comment  you typically want a primitive long  lower-case-l long  not a boxed object long  capital-L Long  for the unixTime variable s type   long unixTime   System currentTimeMillis     1000L
