Answer 1

Answer: To initialize an ArrayList called inventory that stores Car objects in Java, you can use the following code:

import java.util.ArrayList;

public class CarTracker

{

public static void main(String[] args)

{

// Initialize your ArrayList here:

ArrayList<Car> inventory = new ArrayList<>();

}

}

The ArrayList is initialized using the ArrayList<Car> syntax, where Car is the type of objects that will be stored in the ArrayList. The ArrayList is then instantiated using the new ArrayList<>() syntax. You can then add Car objects to the ArrayList using the add method. For example, the following code adds a Car object with the name "Ford", model "Fiesta", and cost $15,000 to the inventory ArrayList:

// Add a Car object to the inventory ArrayList

Car car1 = new Car("Ford", "Fiesta", 15000);

inventory.add(car1);

You can add as many Car objects to the inventory ArrayList as you need. To retrieve a Car object from the ArrayList, you can use the get method and specify the index of the Car object you want to retrieve. For example, the following code retrieves the first Car object in the inventory ArrayList:

// Get the first Car object in the inventory ArrayList

Car car = inventory.get(0);

You can then access the fields of the Car object using the dot notation, as shown in the following code:

// Print the name, model, and cost of the Car object

System.out.println("Name: " + car.name);

System.out.println("Model: " + car.model);

System.out.println("Cost: $" + car.cost);

This code would output the name, model, and cost of the Car object.
