// Working with Instant in Java
import java.time.Instant;
import java.time.ZoneId;
import java.time.format.DateTimeFormatter;
public class InstantExample {
public static void main(String[] args) {
// Get the current instant
Instant now = Instant.now();
System.out.println("Current Instant: " + now);
// Convert to a specific timezone
ZoneId zoneId = ZoneId.of("America/New_York");
String formattedDate = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
.withZone(zoneId)
.format(now);
System.out.println("Formatted Date in New York: " + formattedDate);
}
}
