8. Which of the following defines information hiding A. nformation hiding is hiding as much detail about your class as possible so others can t I steal it. B. nformation hiding is about hiding implementation details and protecting variables from I being used the wrong way. C. nformation hiding is used to obscure the interworking of your class so external classes must I use the public interface. Answer:
3 B . Good class design hides as many methods and instance variables as possible. This is done by using the private access modifier. This is so external objects do not try to interact with the object in ways the developer has not intended. Hiding information makes code easier to maintain and more modular.
and C are incorrect. A is incorrect because information hiding has nothing to do with A protecting your code from others. C is incorrect because access modifiers should be used to force external classes to use the proper public interface. 9. What access modifier is used to make the instance variable or method only available to the class it is defined in A. public B. private C. protected D. package-private (default) Answer:
3 B . The private access modifier is used to allow only the methods in the class to access the method or instance variable.
A, C,and D are incorrect. A is incorrect because public would make the instance variable available to every class. C is incorrect because protected would make the instance variable available to any subclass or class in the same package. D is incorrect because package-private, or the default access level, would make the instance variable available to any other class in the same package.

Understanding Class Inheritance
10. What access modifier is used to create an interface for other objects regardless of their package or their base classes A. public B. private C. protected D. package-private (default) Answer:
3 A . The public access modifier allows any object in the application to access the instance variable or method.
B, C,and D are incorrect. B is incorrect because private would make the method only available to the class it is defined in. C is incorrect because protected would make the method only available to subclasses and classes defined in the same package. D is incorrect because package-private, or the default access level, would make the method only available to classes defined in the same package.
