Monthly Period

Instructions

Create a class MonthlyPeriod that provides a method to calculate the period between two given dates in terms of months and years. The dates will be provided in the format yyyy-MM-dd.

In case of any error the method calculatePeriod should return Error

💡 Going to the past is possible!

Expected Class

import java.time.LocalDate;
import java.time.Period;
import java.time.format.DateTimeFormatter;

public class MonthlyPeriod {
    public String calculatePeriod(String startDate, String endDate) {
        // Implementation to calculate the period between two dates in months and years
    }
}

Usage

Here is a possible ExerciseRunner.java to test your class:

public class ExerciseRunner {
    public static void main(String[] args) {
        MonthlyPeriod MonthlyPeriod = new MonthlyPeriod();

        String startDate1 = "2020-01-01";
        String endDate1 = "2023-06-15";
        System.out.println("Period: " + MonthlyPeriod.calculatePeriod(startDate1, endDate1));

        String startDate2 = "2015-05-20";
        String endDate2 = "2015-10-20";
        System.out.println("Period: " + MonthlyPeriod.calculatePeriod(startDate2, endDate2));

        String startDate3 = "2018-12-25";
        String endDate3 = "2021-12-25";
        System.out.println("Period: " + MonthlyPeriod.calculatePeriod(startDate3, endDate3));

        String startDate3 = "2018-10-25";
        String endDate3 = "2019-11-30";
        System.out.println("Period: " + MonthlyPeriod.calculatePeriod(startDate3, endDate3));
    }
}

Expected Output

$ javac *.java -d build
$ java -cp build ExerciseRunner
Period: 3 years and 5 months
Period: 5 months
Period: 3 years
Period: 1 year and 1 month
