September 17, 2022 - ArrayList is based on zero based indexing, which means first element is present at the index 0. The other elements in the ArrayList are shifted, which means after adding new element to the front, the first element becomes second, second element becomes third and so on. import java.util.ArrayList; public class JavaExample{ public static void main(String[] args) { ArrayList<String> arrList = new ArrayList<>(); arrList.add("Ram"); // [Ram] arrList.add("Steve"); // [Ram, Steve] arrList.add("John"); // [Ram, Steve, John] // instead of adding the element at the end, we are // adding the element in the beginning using // add(int index, Object element) method variation arrList.add(0, "Chaitanya"); System.out.println(arrList); } }
