Select the correct answer.

Answer explanation

  1. In the beginning the order of the elements of the array pLanguage is
    Java C++ Ruby Perl Python
  2. The statement Arrays.sort(pLanguage); orders the elements of the array alphabetically as follows: C++ Java Perl Python Ruby
  3. The conditional statement if (i == 2 || i == 4) is only true for the second and forth elements. The second element isn’t Java but Perl, because the index of arrays starts from zero. The fourth element is Ruby. Therefore the program writes Perl Ruby to the standard output.

The correct answer is: b.
