How do I calculate periods using Java 8 Date Time API?

You can use the Period class in Java 8 to calculate periods between two dates. Would you like a code example?

Yes, please provide a code example.

Sure! Here's a simple example:

import java.time.LocalDate;
import java.time.Period;

public class PeriodExample {
    public static void main(String[] args) {
        LocalDate startDate = LocalDate.of(2020, 1, 1);
        LocalDate endDate = LocalDate.of(2023, 1, 1);
        Period period = Period.between(startDate, endDate);
        System.out.println("Period: " + period.getYears() + " years, " + period.getMonths() + " months, " + period.getDays() + " days.");
    }
}

What if I want to add a period to a date?

You can use the plus method of the LocalDate class. For example:

LocalDate newDate = startDate.plus(period);

Can I also calculate periods in months or days?

Yes, you can create a Period with specific months and days using Period.ofMonths(int months) or Period.ofDays(int days). Would you like more details?
