We would like to know how to convert Instant to java.util.Date.
import java.math.BigInteger; import java.time.Instant; import java.util.Date; /*from w w w . ja v a 2s . co m*/ public class Main { public static void main(String[] args) { Instant i = Instant.now(); System.out.println(toDate(i)); } public static Date toDate(Instant instant) { BigInteger milis = BigInteger.valueOf(instant.getEpochSecond()).multiply( BigInteger.valueOf(1000)); milis = milis.add(BigInteger.valueOf(instant.getNano()).divide( BigInteger.valueOf(1_000_000))); return new Date(milis.longValue()); } }
The code above generates the following result.
