14. E. The class elements declared in lines 5, 8, and 12 are badly named methods, not constructors. The default constructor runs with no output, and these methods are never called. A, B, C, D, and F are incorrect because of the logic described above. 15. C. Only C is correct because the Dog class does not have a no-arg constructor; therefore, you must explicitly make the call to super(), passing in a string. A, B, and D are incorrect based on the program logic described above. 16. B and D are simply stating two rules about constructors. A is wrong because subclass constructors do not have to match the arguments of the superclass constructor. Only the call to super() must match. C is incorrect because constructors can be and are frequently overloaded.

17. C. Byte is a wrapper object, not a primitive. A and D are primitives that are shorter than int so they are cast implicitly. B is a double explicitly cast to an int. E is a valid integer initialized with a hexadecimal value. 18. B and E. B won t compile because the long cast only applies to x, not to the expression x / y. (We know it s tricky, but so is the test.) E won t compile because the result of (y / x) is a float. A, C, D, and F all return either longs or ints (which are automatically cast to longs). 19. D and F. D is a reference to a char primitive that happens to be in an array. F returns a primitive, not an object. A, B, C, and E all return objects. For A, null is always a valid object return. For C, an array is an object that holds other things (either objects or primitives). For E, we are returning an array held in an array, and it s still an object! 20. B and F are both attempting to cast a primitive to an object can t do it. A, C, D, and E all return objects. A is an array object that holds other arrays. C is an array object. D is an ArrayList object. E is a string cast to an object. 21. B. Line 8 is an example of a polymorphic return type. The VM will determine on a caseby-case basis what class of object f2 refers to, Bar or Foo. This is only possible because the classes Foo and Bar are in the same inheritance tree. A, C, D, and E, are incorrect based on the logic described above.

his chapter focuses on the aspects of the java.lang package that you ll need to understand for the exam. The java.lang package contains many of the most fundamental and often-used classes in the Java API. The exam will test your knowledge of String and StringBuffer basics, including the infamous immutability of String objects, and how the more common String and StringBuffer methods work. You will be tested on many of the basic methods included in the Math class (extremely interesting), and you will need to know all about wrappers those methods that allow you to encapsulate your favorite primitives into objects, so that you can do object-like stuff with them (like put them in collections). Finally, we ll reveal more than you ve ever wanted to know about how the equals() method and == operator work when dealing with String objects and wrappers.

As always, our focus will be on the knowledge you ll really need to pass the exam. Undoubtedly some very wonderful methods will be overlooked in our tour of java.lang, but we re dedicated to helping you pass this test.
