- ArithmeticException – It throws ArithmeticException, if the amount of years, months or days exceeds an int.
Below program illustrate the above method:
// Java code to show the function from()// which represents the period of given amountimport java.time.Period;  public class PeriodClassGfG {      // Function to convert given amount to period    static void convertToPeriod(int year, int months, int days)    {        Period period = Period.from(Period.of(year, months, days));          System.out.println(period);    }      // Driver code    public static void main(String[] args)    {          int year = 20, months = 13, days = 17;        Period period = Period.from(Period.of(year, months, days));          convertToPeriod(year, months, days);    }} |
