Period from() method in Java with Examples

The from() method of Period class in Java is used to get an instance of Period from given temporal amount. This function obtains a period based on the amount given in argument. A TemporalAmount represents an amount of time, which may be date-based or time-based. Syntax:

public static Period from(TemporalAmount amount)

Parameters: This method accepts a single parameter amount. This amount is the amount that we need to convert into period. Return Value: This function returns the period equivalent to the given amount. Exceptions:

• DateTimeException - It throws DateTimeException, if unable to convert to a Period.
• ArithmeticException - It throws ArithmeticException, if the amount of years, months or days exceeds an int.

Below program illustrate the above method: Java

// Java code to show the function from()
// which represents the period of given amount
import 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);
    }
}
