Question
What is the output of the following code snippet?ArrayList<Integer> numbers = new ArrayList<>();numbers.add(1);numbers.add(2);numbers.add(3);System.out.println(numbers.get(2));
Solution
The output of the code snippet will be 3.
Here's the step by step explanation:
- An ArrayList of Integer type is created named 'numbers'.
- The number 1 is added to the ArrayList. It becomes the first element, so its index is 0.
- The number 2 is added to the ArrayList. It becomes the second element, so its index is 1.
- The number 3 is added to the ArrayList. It becomes the third element, so its index is 2.
- The get() method is called with the parameter 2, which refers to the third element in the ArrayList (since indexing starts at 0).
- Therefore, the number 3 is printed.
