What is the output of the following code?int[] myList = {1, 2, 3, 4, 5, 6};for (int i = myList.length - 2; i >= 0; i--) { myList[i + 1] = myList[i];}for (int e: myList) System.out.print(e + " "); Group of answer choices1 2 3 4 5 66 1 2 3 4 51 1 2 3 4 56 2 3 4 5 1
Solution
The output of the code will be "1 1 2 3 4 5".
Here's the step by step explanation:
-
The first loop starts from the second last element of the array (myList.length - 2) and goes till the first element (i >= 0).
-
In each iteration, it assigns the value of the current element (myList[i]) to the next element (myList[i + 1]).
-
This effectively shifts all elements of the array one position to the right, starting from the second last element up to the first element.
-
The last element (6) is replaced by the second last element (5), the second last element is replaced by the third last element (4), and so on.
-
The first element (1) is duplicated because it is assigned to the second element.
-
The final array becomes {1, 1, 2, 3, 4, 5}.
-
The second loop simply prints all elements of the array, resulting in "1 1 2 3 4 5".
