Example 13 with ChronoPeriod

the class Period method from.

//-----------------------------------------------------------------------
/**
     * Obtains an instance of {@code Period} from a temporal amount.
     * <p>
     * This obtains a period based on the specified amount.
     * A {@code TemporalAmount} represents an  amount of time, which may be
     * date-based or time-based, which this factory extracts to a {@code Period}.
     * <p>
     * The conversion loops around the set of units from the amount and uses
     * the {@link ChronoUnit#YEARS YEARS}, {@link ChronoUnit#MONTHS MONTHS}
     * and {@link ChronoUnit#DAYS DAYS} units to create a period.
     * If any other units are found then an exception is thrown.
     * <p>
     * If the amount is a {@code ChronoPeriod} then it must use the ISO chronology.
     *
     * @param amount  the temporal amount to convert, not null
     * @return the equivalent period, not null
     * @throws DateTimeException if unable to convert to a {@code Period}
     * @throws ArithmeticException if the amount of years, months or days exceeds an int
