Java Instant plusNanos() method

The plusNanos() method of Java Instant class is used to return a copy of the instant with the specified duration in nanoseconds added

This instance is immutable and unaffected by this method call.

Syntax

Parameter

nanosToAdd ? It specifies the nanoseconds to add. It can be either positive or negative.

Return

It returns an Instant based on this instant with the specified nanoseconds added
he return value cannot be null.

Exception

DateTimeException - If the result exceeds the maximum or minimum instant

ArithmeticException - If numeric overflow occurs

Example 1

import java.time.Instant;

public class InstantPlusNanosExample1 {
  public static void main(String[] args) {
    Instant instant = Instant.parse("2018-02-03T10:15:30.00Z");
    instant = instant.plusNanos(10000);
    System.out.println(instant);
 
  }
}

Output:

2018-02-03T10:15:40Z

Example 2

import java.time.Instant;

public class InstantPlusNanosExample2 {
   public static void main(String args[]) {

      Instant i = Instant.parse("2018-02-03T10:37:30.00Z");
      System.out.println(i.getNano());  
      Instant r = i.plusNanos(70000);
      System.out.println(r.getNano());   
   }
}

Output:

0
70000

Example 3

import java.time.Instant;

public class InstantPlusNanosExample3 {

    public static void main(String... args) {
        Instant i1 = Instant.now();
        System.out.println(i1);

        Instant i2 = i1.plusNanos(2000000);
        System.out.println(i2);

        Instant i3 = i1.plusNanos(-2000000);
        System.out.println(i3);
    }
}

Output:

2018-05-01T20:57:16.073Z
2018-05-01T20:57:16.075Z
2018-05-01T20:57:16.070Z
