Question

The printRightToLeft method is intended to print the elements in the ArrayList words in reverse order. For example, if words contains ["jelly bean", "jukebox", "jewelry"], the method should produce the following output.

jewelry

jukebox

jelly bean

The method is shown below.

public static void printRightToLeft(ArrayList<String> words)

{

if (words.size() > 0)

{

System.out.println(words.get(words.size() - 1));

/* missing code */

}

Which of the following can be used to replace /* missing code */ so that the printRightToLeft method works as intended?

words.remove(0);

printRightToLeft(words);

words.remove(0); printRightToLeft(words);
words.remove(words.size());

printRightToLeft(words);

words.remove(words.size()); printRightToLeft(words);
words.remove(words.size() - 1);

printRightToLeft(words);

words.remove(words.size() - 1); printRightToLeft(words);
printRightToLeft(words);

words.remove(0);

printRightToLeft(words); words.remove(0);
printRightToLeft(words);

words.remove(words.size() - 1);
