Consider the following class; what method would you call to achieve starting the engine? 
public class Car {
    private String make;
    private String model;

    // Constructor creates a Car object with identifying information.
    public Car(String make, String model) {
        this.make = make;
        this.model = model;
    }

    // startEngine prints a message using stored fields.
    public void startEngine() {
        System.out.println("Engine started: " + make + " " + model);
    }

    public static void main(String[] args) {
        Car myCar = new Car("Ford", "Focus");
