private void usingArrayList() {
 ArrayList<String> list = new ArrayList<>(Arrays.asList("cat", "cow", "dog"));
 list.add("fish");
 int size = list.size(); // size = 4
 list.set(size - 1, "horse"); // replacing the last element to "horse"
 String removed = list.remove(1); // removed = "cow"
 String second = list.get(1); // second = "dog"
}
