Examice · Accepted Answer

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].
