This statement describes a successful assignment, which cannot happen as the field `year` does not exist in the `Student` class, preventing successful compilation.

This statement also describes a successful assignment to a non-existent field, which will cause a compilation error, not a successful assignment.

The error occurs during compilation, not at runtime, because Java's strong type checking identifies the undefined field `year` before the code can ever be executed.

The `Student` class definition does not include a member variable named `year`. Therefore, attempting to assign a value to `bob.year` in the `TestStudent` class will cause a compile-time error because the Java compiler cannot find a matching field for `year` on the `Student` object.
