Answer 13

Question 14

True or False? There is a class named Arrays that contains various methods for manipulating arrays (such as sorting and searching) . The Arrays class contains many overloaded versions of the sort method. As usual, each overloaded version of the sort method requires a different argument list.

Answer 14

Question 15

Given: Listing 1 makes two calls to overloaded sort methods of the Arrays class using the following overloaded methods. (Note that I omitted generics syntax from the signatures because generics is beyond the scope of this course .)

  • sort(Object[] a)
  • sort(Object[] a, Comparator c)

True or False? In Listing 1 , the call to the first sort method in the above list produces the following output:

Question 16

True or False? In Listing 1 , the call to the second sort method in the above list produces the following output:

Answer 16

True.

Back to Question 16

Answer 15

False. Here is what the documentation has to say about this overloaded version of the Arrays.sort method:

Sorts the specified array of objects into ascending order, according to the natural ordering of its elements. All elements in the array must implementthe Comparable interface.

According to that specification, the output would be:

Answer 12

True.

Back to Question 12

Answer 11

False. By default, a Vector object does not sort the elements. Therefore, the output order is the same as the input order shown inthe fillIt method.

Answer 8

False. The position of each element in an ordered collection is determined by a numeric index associated with the element and is independent ofthe value of the element.

Back to Question 8

Answer 7

True.

Back to Question 7

Answer 6

False. Because a Vector object is a List object, (and not a Set object) it is allowed to contain duplicate elements.

Back to Question 6

Answer 5

False. A Vector object is a List object. The Vector class implements the Collection interface and the List interface but not the Set interface.

Answer 2

True.

Back to Question 2

Answer 1

False. The Collection interface declares a method named toArray , which can be called on a Collection object to "return an array containing all of the elements in this collection whose runtime type is that ofthe specified array" .
