Question

I would like to obtain the string text of the elements stored in a list, say List<Car>. Would the toArray() and the toString() methods be the best options?

Answer 1

Yes, but doing it manually gives you more control:

// initialize with the exact length
List<String> stringsList = new ArrayList<String>(listOfCars.size()); 
for (Car car : listOfCars) {
    stringsList.add(car.toString());   
}

If you haven’t overridden the toString() method or don’t want to override it, you can use car.getName() instead of car.toString() (or any property combination you like)
