# LocalTime minusNanos() method in Java

Java 8Object Oriented ProgrammingProgramming

An immutable copy of a LocalTime object where some nanoseconds are subtracted from it can be obtained using the minusNanos() method in the LocalTime class in Java. This method requires a single parameter i.e. the number of nanoseconds to be subtracted and it returns the LocalTime object with the subtracted nanoseconds.

A program that demonstrates this is given as follows −

## Example

Live Demo

import java.time.*;
public class Demo {
public static void main(String[] args) {
LocalTime lt = LocalTime.now();
System.out.println("The current LocalTime is: " + lt);
System.out.println("The LocalTime with 1000 nanoseconds subtracted is: " + lt.minusNanos(1000));
}
}

## Output

The current LocalTime is: 09:50:27.314
The LocalTime with 1000 nanoseconds subtracted is: 09:50:27.313999

Now let us understand the above program.

First the current LocalTime is displayed. Then an immutable copy of the LocalTime where 1000 nanoseconds are subtracted is obtained using the minusNanos() method and this is displayed. A code snippet that demonstrates this is as follows −

LocalTime lt = LocalTime.now();
System.out.println("The current LocalTime is: " + lt);
System.out.println("The LocalTime with 1000 nanoseconds subtracted is: " + lt.minusNanos(1000));
