What is the result of the .map(Object::toString) method when processing collection elements?

The .map(Object::toString) method, when processing collection elements, converts each element to its string representation by calling the toString() method on each object. As a result, a new collection (such as a Stream or List) is created, consisting of strings corresponding to the original objects.

Example in Java using the Stream API:

List<Integer> numbers = List.of(1, 2, 3);
List<String> strings = numbers.stream()
    .map(Object::toString)
    .collect(Collectors.toList());

// strings will contain: ["1", "2", "3"]
