Answer
When sharing state or providing constructor logic is needed.
Abstract classes are suitable when you need to share state or provide constructors among classes. They can hold instance variables and concrete methods with access to class fields. For example, 'AbstractProduct' might store a 'price' field and provide a constructor to initialize it, which isn't possible with interfaces.
