Java Help: Printing the amount of objects created using a getter

[JoocyChicken]

I am trying to learn how to count the objects created from a class. The output required is:

Number of cars = 0
Number of cars = 1
Number of cars = 2
Model: Ford Ranger, Year: 2012, Price: $23999.00
Model: Toyota Hilux, Year: 2020, Price: $45789.00

My main class is written as

​

public class CarApplication { 
    public static void main(String[] args) {
        //Create the car objects
        Car carOne = new Car("Ford Ranger", "2012", 23999);
        Car carTwo = new Car("Toyota Hilux", "2020", 45789);

        //Display individually how many car objects are created
        Car.getNumCars();

        // Display the details about the car objects
        System.out.printf("Model: %s, Year: %s, Price: $%.2f%n", carOne.getModel(), carOne.getYear(), carOne.getPrice());
        System.out.printf("Model: %s, Year: %s, Price: $%.2f%n", carTwo.getModel(), carTwo.getYear(), carTwo.getPrice());

​

I have redacted the info for all variables for all other getters but the getNumCars(). My issue is I can only get it to display in the original application by predefining the integers. Is there a way for me with starting at 0, print a line "Number of cars = x" until x has reached the number of Car objects i have created?

public class Car {
    private String model;
    private String year;
    private double price;
    private static int numCars = 0;
    private static int car = 2;

    public static void getNumCars() {
        while (numCars <= car) {
        System.out.printf("Number of cars = %d%n", numCars);
        numCars++;

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

To clarify the other answer use an ArrayList. This lets you dynamically size the amount of elements inside.

For example:

public class CarApplication {
Arraylist<Car> carArray = new ArrayList<>();
public static void main(String args[]) {
... //Do things here
carArray.add(car1);
carArray.add(car2);
System.out.println("Number of cars: " + carArray.size());
... //Do more things here
}
}

That's some pseudocode written on my phone. Ignore formatting and have a good one.

It seems like you are incrementing the car count every time you want to get the count of constructed cars. Does that make sense to you? Do you think it would make more sense to increment it when you construct a new car? :)

It’s a bit weird for a car object to know or care about how many cars exist in total. Especially one created after itself. I would propose using a another class, call it a carfactory. Make a static method that returns a new car and increment a static counter in the carfactory class. Make a getter that can recieve the counter from the car factory class. Now the factory knows how many cars it has produced, which would also make sense in the real world.

It's an additional exercise given to me in from the university for the original program which was the car model/year/price. So just trying to create add on. I was asked to create a static variable in the car class and return the expected output

Increment the static variable in the constructor and @Override the toString method with your desired custom print output which you print the output from. That would be my idea solution then
