What mechanism does Fill2Test use to adapt a specific type?

Inheritance
Abstract Classes
Singletons
Static utility methods

The correct answer is: Inheritance

Fill2Test uses inheritance as its mechanism to adapt a specific type. Inheritance allows a class to inherit properties and methods from another class, making it a useful feature for adapting specific types of data structures. The other options listed - namely abstract classes, singletons, and static utility methods - do not offer the same level of adaptability and flexibility in adapting data types. Abstract classes can only inherit from one class, singletons are limited to a single instance, and static utility methods do not allow for the creation of new instances. Therefore, inheritance is the best mechanism for adapting a specific type in Fill2Test.
