The plusMillis() method of Instant class adds specified duration in milliseconds to this instant and returns the result as an instant object. This returned Instant is immutable.
Syntax:
public Instant plusMillis(long millisToAdd)
Parameters: This method accepts one parameter millisToAdd which is milliseconds to add.
Returns: This method returns Instant with the milliseconds added to it.
Exception: This method throws following exceptions:
- DateTimeException: if the result exceeds the maximum or minimum instant.
- ArithmeticException: if numeric overflow occurs.
Below programs illustrate the plusMillis() method:
Program 1:
// Java program to demonstrate// Instant.plusMillis() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant            = Instant.parse("2018-12-30T19:34:50.63Z");          // addition of 8800000 MILLI_OF_SECOND        // means 8800 seconds to this instant        Instant returnedValue            = instant.plusMillis(8800000);          // print result        System.out.println("Returned Instant: "                           + returnedValue);    }} |
Program 2:
// Java program to demonstrate// Instant.plusMillis() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a Instant object        Instant instant = Instant.now();          // current Instant        System.out.println("Current instant: "                           + instant);          // addition of 420000 MILLI_OF_SECOND        // means 420 seconds to this instant        Instant returnedValue            = instant.plusMillis(420000);          // print result        System.out.println("Returned Instant: "                           + returnedValue);    }} |
