Question 103

Given the code fragment:

What is the result?

    Correct Answer: C

    In the provided code fragment, two ArrayLists are created and manipulated. For the first list, vegetables, 'Kale' is added first, followed by 'Lettuce' added at index 0, making the list ['Lettuce', 'Kale']. For the second list, fish, 'Salmon' is added first, followed by 'Seabass' added at index 0, making the list ['Seabass', 'Salmon']. When both lists are printed, the output will be [Lettuce, Kale] for the vegetables list and [Seabass, Salmon] for the fish list. Therefore, the correct result is [Lettuce, Kale] [Seabass, Salmon].

Discussion
ASPushkinOption: C

AbstractCollection already overrides toString() to print the contents of its elements. So, just list.toString() prints the toString() of all its elements. This is true for all collections. public StringBuilder append​(Object obj) Appends the string representation of the Object argument.
