The minusNanos(long) method of Duration Class in java.time package is used to get an immutable copy of this duration with the specified number of nano-seconds subtracted, passed as the parameter.
Syntax:
public Duration minusNanos(long numberOfNanos)
Parameters: This method accepts a parameter numberOfNanos which is the number of nano-seconds to be subtracted. It can be positive or negative but not null.
Return Value: This method returns a Duration which is an immutable copy of the existing duration with the parameter amount of nano-seconds subtracted to it.
Exception: This method throws ArithmeticException if numeric overflow occurs.
Below examples illustrate the Duration.minusNanos() method:
Example 1:
Java
// Java code to illustrate minusNanos() method import java.time.Duration; public class GFG { public static void main(String[] args) { // Duration 1 using parse() method Duration duration1 = Duration.parse( "P2DT3H4M" ); // Get the duration subtracted // using minusNanos() method System.out.println(duration1.minusNanos( 2 )); } } |
