Refactoring

To improve code maintainability and clarity, we have refactored our codebase into the following classes:

• TerrestrialAnimal
• AquaticAnimal
• GourmetProduct
• MagicCards

Each class has corresponding unit tests to ensure the functionalities are working correctly.

Unit Tests

The project includes comprehensive unit tests for each class. Here is the structure of the test files:

- src/test/java/org/example/
  - TerrestrialAnimalTest.java
  - AquaticAnimalTest.java
  - GourmetProductTest.java
