What is printed as a result of executing the following code segment? ArrayList aList = new ArrayList<Integer>(); aList.add(1); aList.add(2); aList.remove(1); aList.add(1, 3); aList.set(1, 4); aList.add(5); System.out.println(aList); A) [1, 4, 5] B) [2, 4, 5] C) [1, 2, 3, 4, 5] D) [1, 4, 3, 5]
Understand the Problem
The question is asking for the final output of a sequence of operations performed on an ArrayList in Java. We need to carefully trace through the code step by step to determine the state of the ArrayList after each operation, leading to the final printed result.
Answer
[1, 4, 5]
The final answer is [1, 4, 5]
Answer for screen readers
The final answer is [1, 4, 5]
More Information
When the ArrayList aList is executed, the result is [1, 4, 5] after performing all the operations listed in the code segment.
Tips
A common mistake is misunderstanding the effect of remove() and set() methods and their indexing. remove(1) deletes the element at index 1, not the integer 1.
