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.

    {
        // 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);
    }
