import java.util.ArrayList;

public class Main {
  public static void main(String[] args) {
    ArrayList<String> arrayList = new ArrayList<String>();

    arrayList.add("1");
    arrayList.add("2");
    arrayList.add("3");

    int totalElements = arrayList.size();
    for (int index = 0; index < totalElements; index++)
      System.out.println(arrayList.get(index));
  }
}
