ChronoPeriod multipliedBy() method in Java with Examples

Last Updated : 24 Jun, 2019

The multipliedBy() method of ChronoPeriod interface in Java is used to return a new instance of ChronoPeriod after multiplying 'X' (a scalar quantity) each element of the period YEAR, MONTH, DAY from a given period. This function operate only on all three YEAR, MONTHS, DAYS. Syntax:

public ChronoPeriod multipliedBy(int toMultiply)

Parameters: This method accepts a single parameter toMultiply which is the scalar number to be multiplied to the period. Return Value: This method returns a new instance of ChronoPeriod after multiplying each element of the period with the given toMultiply input. Exceptions: It throws an ArithmeticException.This exception is caught if numeric overflow occurs. Below is the implementation of the above method: Program 1:

Java

// Java code to show the function multipliedBy()
// to multiply the given number to given period

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to multiply a constant to given periods
    static void multiply(ChronoPeriod p1, int toMultiply)
    {
        System.out.println(p1.multipliedBy(toMultiply));
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining first period
        int year = 4;
        int months = 11;
        int days = 10;
        ChronoPeriod p1 = Period.of(year, months, days);

        int toMultiply = 2;

        multiply(p1, toMultiply);
    }
}

Output:

P8Y22M20D

Program 2:

Java

// Java code to show the function multipliedBy()
// to multiply the given number to given period

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to multiply a constant to given periods
    static void multiply(ChronoPeriod p1, int toMultiply)
    {
        System.out.println(p1.multipliedBy(toMultiply));
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining first period
        int year = -4;
        int months = -11;
        int days = -10;
        ChronoPeriod p1 = Period.of(year, months, days);

        int toMultiply = 2;

        multiply(p1, toMultiply);
    }
}
