Object Creation and Storage (Instantiation) Practice Test

Given the code below, which line of code correctly creates an object of Customer?

public class Customer {

    private String name;

    // Constructor creates a customer with a stored name.

    public Customer(String name) {

        this.name = name;

    }

    // getName returns the customer's name.

    public String getName() {

        return name;

    }

}

class Order {

    private Customer customer;

    // Constructor stores a reference to a Customer object.

    public Order(Customer customer) {

        this.customer = customer;

    }

    // printReceipt uses the nested object's method.

    public void printReceipt() {

        System.out.println("Customer: " + customer.getName());

    }

    public static void main(String[] args) {

        // Objects are instantiated and then used together.

        // Example method invocation on an instantiated object:

        // order.printReceipt();

    }

}

Given the code below, what method would you call to achieve changing the car's model label?

public class Car {

    private String make;

    private String model;

    // Constructor creates a Car object stored in a reference.

    public Car(String make, String model) {

        this.make = make;

        this.model = model;

    }

    // repaint updates the model field.

    public void repaint(String newModelLabel) {

        model = newModelLabel;

    }

    public static void main(String[] args) {

        Car myCar = new Car("Toyota", "Corolla");

        // The object is manipulated after instantiation.

    }

}
