Convert a List (ArrayList) to an Array

This piece of Java code shows how to convert a List, in this case an ArrayList, to an Array by calling the method toArray() on the List object.
The toArray() method returns an array of the same type as the array provided as an argument to the method. The argument can be an empty array as in the example below.

/**

 */
public class Main {
    
    public void ListToArray() {
        
        List<String> carList = new ArrayList<String>();
        
        carList.add("Dodge");
        carList.add("Chevrolet");
        carList.add("BMW");
        carList.add("Toyota");
        
        String[] carArray = carList.toArray(new String[0]);
        
        for (String car : carArray) {
            System.out.println(car);
        }
    }
 
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main().ListToArray();
    }
}
