    In Java, the ArrayList class is used to create a resizable array, which can be found in the java.util package. Unlike standard arrays, an ArrayList can grow and shrink dynamically as elements are added or removed.

    Example

    import java.util.ArrayList;

    public class Main {
    public static void main(String[] args) {
    // Create an ArrayList to store String elements
    ArrayList<String> cars = new ArrayList<String>();

    // Add elements to the ArrayList
    cars.add("Volvo");
    cars.add("BMW");
    cars.add("Ford");
    cars.add("Mazda");

    // Print the ArrayList
    System.out.println(cars);
    }
    }
    Gekopieerd.

    Adding Elements

    To add elements to an ArrayList, use the add() method. You can add elements at the end of the list or at a specific index.

    cars.add("Toyota"); // Adds "Toyota" at the end
    cars.add(1, "Honda"); // Adds "Honda" at index 1
    Gekopieerd.

    Accessing Elements

    To access elements in an ArrayList, use the get() method and refer to the index number.

    String car = cars.get(0); // Accesses the first element
    Gekopieerd.
