### UML Class Diagram: Class Casting for Rectangle

**Question:** Based on the UML class diagram below, name all the classes that an object of the `Rectangle` class can be casted to.

**Diagram Explanation:** 

The diagram represents a hierarchy of classes in a Unified Modeling Language (UML) format. Each rectangle in the diagram represents a class, and the arrows indicate inheritance relationships (with the arrow pointing to the parent class from the child class). Below is the detailed description:

- **Object:** The topmost parent class in the hierarchy.
  - **Shape:** Directly inherits from `Object`.
    - **OneDimensionalShape:** A subclass of `Shape`.
    - **TwoDimensionalShape:** Another subclass of `Shape`. 
      - **Circle:** A subclass of `TwoDimensionalShape`.
      - **Rectangle:** A subclass of `TwoDimensionalShape`.
        - **Square:** A subclass of `Rectangle`.
    - **ThreeDimensionalShape:** Another subclass of `Shape`.

**Classes an Object of `Rectangle` Can be Casted To:**

1. **Object:** The ultimate parent class.
2. **Shape:** The immediate parent class of `TwoDimensionalShape`.
3. **TwoDimensionalShape:** The direct parent class of `Rectangle`.
4. **Rectangle:** The class itself.

Additionally, since a `Square` is a subclass of `Rectangle`, an object of the `Rectangle` class can be casted to the `Square` class, but it might lose part of its specificity in doing so.

 Therefore, an object of the `Rectangle` class can be cast to the following classes:

- Object
- Shape
- TwoDimensionalShape
- Rectangle
