Can't pass the 5th condition even though the program ran without any error in IntelliJ.

Question about the task

Under discussion

CodeGym says, "It looks like the factory method handles the ApplicationExceptionMessage enum incorrectly." Could someone point out what can be corrected to pass the test?

Create an exception factory class that has a single static method that returns the required exception.
This method should accept one enum argument.
Do the following for each of these enums:
* ApplicationExceptionMessage: return an Exception
* DatabaseExceptionMessage: return a RuntimeException
* UserExceptionMessage: return an Error otherwise: return IllegalArgumentException without a message.

Use the name of the enum field as the message of the returned object, replacing all of the underscores with spaces. Everything must be lowercase except the first character of the message.
For example, the message for ApplicationExceptionMessage.SOCKET_IS_CLOSED should be "Socket is closed".

Return the created factory class in the Solution.getFactoryClass method.

Don't change the enums.

Requirements:

The getFactoryClass method must return the exception factory.
ApplicationExceptionMessage must not have any additional methods or constructors.
DatabaseExceptionMessage must not have any additional methods or constructors.
UserExceptionMessage must not have any additional methods or constructors.
The static exception factory method must return the exceptions listed in the conditions (including the message) for any inputs.
The factory must have one method and it must be static.

package com.codegym.task.task38.task3804; public class Solution { public static Class getFactoryClass() { return ExceptionFactory.class; } public static void main(String[] args) { } }

"Use the name of the enum field as the message of the returned object, replacing all of the underscores with spaces. Everything must be lowercase except the first character of the message. For example, the message for ApplicationExceptionMessage.SOCKET_IS_CLOSED should be "Socket is closed"." I used the following:

String message = e.name().substring(0, 1) + e.name().substring(1).replaceAll("_", " ").toLowerCase();

After that it said it didn't handle null values properly. So I replaced all the == with .equals() and made the first condition check if the Enum was null, and made it return an IllegeArgumentException.
