Question

I’m new to Java programming and need to create a method called sizeofCarPark that returns the amount of cars that are stored in a Car Park. I’d appreciate some pointers in what I need to do.

Answer 1

What kind of an Object is a Car Park?

ArrayList already has a size() method.

Example:

public class CarPark {
    private List<Car> cars = new ArrayList<Car>();

    public int sizeOfCarPark() {
        return cars.size();
    }
}
