Consider the following class; what method would you call to achieve starting the engine?

public class Car {
    private String make;
    private String model;
    private boolean engineOn;

    // Constructor initializes a new car with engine off
    public Car(String make, String model) {
        this.make = make;
        this.model = model;
        engineOn = false;
    }

    // Method turns the engine on
    public void startEngine() {
        engineOn = true;
    }

    public static void main(String[] args) {
        // Object is instantiated, then a method is invoked to change its state
        Car myCar = new Car("Honda", "Civic");
        // Invoke the method here
    }
}
