import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

public class Main {
  public static void main(String[] args) {
    List list = new ArrayList();

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

    list.add("java2s.com");

    System.out.println(list);

    Object[] array = list.toArray();

    System.out.println(Arrays.toString(array));
  }
}

The output:
