Can you name classes or objects that are not descendants of the base class Object?

In Java, almost all classes are descendants of the base class Object, as it is the root of the class hierarchy. However, there are exceptions:

• Primitive types (int, boolean, char, etc.) are not objects and, therefore, do not inherit from Object.
• Arrays in Java are objects and inherit from Object.
• Interfaces themselves do not inherit from Object, but classes that implement them do.

Thus, objects that are not descendants of Object are primitive types, as they are not objects in Java.
