how to create arraylist in java

import java.util.ArrayList;
public class ArrayLists {
    public static void main(String[] args) {

        ArrayList<String> cars = new ArrayList<String>();

        cars.add("Volvo");
        cars.add("BMW");
        cars.add("Ford");
        cars.add("Mazda");

        System.out.println(cars); // [Volvo, BMW, Ford, Mazda]
        System.out.println(cars.isEmpty()); // false
        System.out.println(cars.size()); // 4

        cars.remove(0); // removes the element at index 0 (i.e. "Volvo")

        System.out.println();
        System.out.println(cars); // [BMW, Ford, Mazda]
        System.out.println(cars.isEmpty()); // false
        System.out.println(cars.size()); // 3

        cars.remove(1); // removes the element at index 1 (i.e. "Ford")

        System.out.println();
        System.out.println(cars); // [BMW, Mazda]

        cars.add("Mercedes");

        System.out.println();
        System.out.println(cars); // [BMW, Mazda, Mercedes]

        cars.clear();

        System.out.println();
        System.out.println(cars); // []
        System.out.println(cars.isEmpty()); // true
        System.out.println(cars.size()); // 0
  }
