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
