The multipliedBy(long) method of Duration Class in java.time package is used to get an immutable copy of this duration multiplied by the value passed as the parameter.
Syntax:
public Duration multipliedBy(long multiplicand)
Parameters: This method accepts a parameter multiplicand which is the value to be multiplied. It can be positive or negative value.
Return Value: This method returns a Duration which is an immutable copy of the existing duration with the parameter value multiplied to it.
Exception: This method throws ArithmeticException if numeric overflow occurs.
Below examples illustrate the Duration.multipliedBy() method:
Example 1:
// Java code to illustrate multipliedBy() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration 1 using parse() method        Duration duration1            = Duration.parse("P2DT3H4M");          // multiplicand value        long multiplicand = 2;          // Get the duration multiplied        // using multipliedBy() method        System.out.println(duration1                               .multipliedBy(multiplicand));    }} |
Output:
PT102H8M
Example 2:
// Java code to illustrate multipliedBy() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // Duration 1 using parse() method        Duration duration1            = Duration.parse("P2DT3H4M");          // multiplicand value        long multiplicand = 10;          // Get the duration multiplied        // using multipliedBy() method        System.out.println(duration1                               .multipliedBy(multiplicand));    }} |
Output:
PT510H40M
