The minusNanos() method of LocalTime class is used to subtract specified no of nanoseconds value from this LocalTime and return the result as a LocalTime object. This instant is immutable. The calculation wraps around midnight.
Syntax:
public LocalTime minusNanos(long nanosecondsToSubtract)
Parameters: This method accepts a single parameter nanosecondsToSubtract which is the value of nanoseconds to be subtracted, it can be a negative value.
Return value: This method returns a LocalTime based on this time with the nanoseconds subtracted.
Below programs illustrate the minusNanos() method:
Program 1:
// Java program to demonstrate// LocalTime.minusNanos() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("19:34:50.63"); // print LocalTime System.out.println("LocalTime before subtraction: " + time); // subtract 34000000 nanoseconds using minusNanos() LocalTime value = time.minusNanos(34000000); // print result System.out.println("LocalTime after subtraction: " + value); }} |
Output:
LocalTime before subtraction: 19:34:50.630 LocalTime after subtraction: 19:34:50.596
Program 2:
// Java program to demonstrate// LocalTime.minusNanos() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse("01:00:01"); // print LocalTime System.out.println("LocalTime before subtraction: " + time); // subtract 971200000 nanoseconds using minusNanos() LocalTime value = time.minusNanos(971200000); // print result System.out.println("LocalTime after subtraction: " + value); }} |
Output:
LocalTime before subtraction: 01:00:01 LocalTime after subtraction: 01:00:00.028800
