Question about the task

Resolved

I have gone through each and every item and condition to make sure I have implemented correctly, but it fails every test. I feel like there is some type of bug or something or maybe I am just blind. All I know is it passes all the tests I made in my IDE both getEggCount and getDescription works flawlessly for each type of hen...

Write a factory (HenFactory) for making chickens (Hen):

1. Write a Hen class.
1.1. Make it abstract.
1.2. Add an int getMonthlyEggCount() method to the abstract class.
1.3. Add a String getDescription() method to the class. It should return "I am a chicken."
2. Create an NorthAmericanHen class that inherits Hen.
3. Create an EuropeanHen class that inherits Hen.
4. Create an AsianHen class that inherits Hen.
5. Create an AfricanHen class that inherits Hen.
6. In each of these four classes, write your own implementation of the getMonthlyEggCount method.
The method should return the number of eggs per month produced by that type of chicken.
7. In each of these four classes, write your own implementation of the getDescription method.

The method must return a string as follows:
<parent class>.getDescription() + " I come from <continent>. I lay <n> eggs a month."
where <continent> is the name of the continent
and <n> is the number of eggs per month.

8. In the HenFactory class, implement the getHen method. It should return a chicken breed corresponding to the continent that the chicken came from.
9. All the classes you create must be in separate files.

Requirements:

The Hen class must be abstract.
The Hen class must have an abstract int getMonthlyEggCount() method.
The Hen class must implement a String getDescription() method, which returns "I am a chicken."
The NorthAmericanHen, EuropeanHen, AsianHen, and AfricanHen classes must inherit the Hen class and be located in separate files.
The NorthAmericanHen, EuropeanHen, AsianHen, and AfricanHen classes must implement the getMonthlyEggCount method, which should return the number of eggs per month laid by the corresponding type of chicken.
The NorthAmericanHen, EuropeanHen, AsianHen, and AfricanHen must override the parent class's getDescription method so that the returned string looks like this: <parent class>.getDescription() + " I come from <continent>. I lay <n> eggs a month." where <continent> is the name of the continent, and <n> is the number of eggs per month.
The getHen method must be implemented in the HenFactory class and must return the chicken type that corresponds to the passed continent.

package com.codegym.task.task14.task1408; /* Chicken factory */ public class Solution { public static void main(String[] args) { Hen hen = HenFactory.getHen(Continent.AFRICA); hen.getMonthlyEggCount(); } static class HenFactory { static Hen getHen(String continent) { Hen hen; switch (continent) { case Continent.AFRICA: hen = new AfricanHen(); break; case Continent.ASIA: hen = new AsianHen(); break; case Continent.EUROPE: hen = new EuropeanHen(); break; case Continent.NORTHAMERICA: hen = new NorthAmericanHen(); break; default: hen = null; } return hen; } } abstract static class Hen { abstract int getMonthlyEggCount(); String getDescription() { return "I am a chicken."; } } }

nevermind, i figured it out. the answer was to pull the inner static hen class outside of the solution class.
