Language: Javapublic List<Integer> some Function (final List<Integer> numbers) { List<Integer> result new ArrayList<Integer>();for (int i = numbers.size() -1; i >= 0; i--) {result.add(numbers.get(i));12345}6return result;7}Image not displaying?What does this method return?
Solution
Sure, let's break down the method step by step:
- The method takes a list of integers as input, named
numbers. - It initializes an empty list called
resultto store the output. - A for loop is used to iterate over the input list
numbersin reverse order, starting from the last element (indexnumbers.size() - 1) and ending at the first element (index0). - Inside the loop, each element from the input list
numbersis added to theresultlist. - After the loop completes, the
resultlist, which now contains the elements ofnumbersin reverse order, is returned.
So, the method returns a list of integers that is the reverse of the input list numbers.
