Answer
For shared fields and constructor logic. Frame the concept in practical terms so you can explain it during interview discussion.
Abstract classes allow shared state through fields and provide constructors, which interfaces with default methods cannot. They are useful when a common base state or initialization logic is needed across subclasses. For instance, 'AbstractProduct' might maintain a 'price' field and initialize it via a constructor.
