Solution

The following statements are true:

  1. A subclass is a subset of a superclass.
  2. A subclass is usually extended to contain more functions and more detailed information than its superclass.
  3. "class A extends B" means A is a subclass of B.

The statement "class A extends B" means B is a subclass of A is not true. In this context, A is the subclass of B, not the other way around.
