TRUE/FALSE

1. True/False: Procedures, typically, operate on data items that are within the procedure.

ANS: F

2. True/False: The act of declaring a class variable does not actually create an object in memory.

ANS: T

3. True/False: If a constructor is not written when the class is compiled, then a constructor is automatically provided and it is known as the default constructor.

ANS: T

4. True/False: When a superclass method has the same name as a subclass method, it is often said that the superclass method overrides the subclass method.

ANS: F

5. True/False: External entities do not have direct access to the object’s private methods.

ANS: T

6. True/False: When the program is running, it can use the class to create, in memory, one object of a specific type as needed.

ANS: F

7. True/False: The private object fields can be directly manipulated by outside entities.

ANS: F

8. True/False: When a class variable is assigned the address of an object, it is said that the variable references the object.

ANS: T

9. True/False: In an inheritance relationship, the superclass inherits members from the subclass, not the other way around.

ANS: F

10. True/False: When an object’s internal data is hidden from outside code and access to the data is restricted to the object’s methods, the data is protected from accidental corruption.

ANS: T

11. True/False: There are primarily three methods of programming in use today: procedural, recursive, and object-oriented.

ANS: F

12. True/False: The separation of data and the code that operates on the data can lead to problems as a program becomes larger and more complex.

ANS: T
