Question

The following Java code attempts to define an abstract class and use it. Identify the best way to correct the error to allow instantiation of a concrete class. abstract class Vehicle { abstract void start(); void stop() { System.out.println("Vehicle stopped."); } } class Car extends Vehicle { // Missing implementation } public class Main { public static void main(String[] args) { Car myCar = new Car(); myCar.start(); } }

o In Java, if a class like Vehicle has an abstract method start, then that class itself must be declared abstract. o Any concrete class a class that can be instantiated, like Car is intended to be that extends an abstract class must provide an implementation for all inherited abstract methods. o Since Car does not implement start, it is implicitly abstract and cannot be instantiated. To fix this, Car needs to provide a concrete implementation for the start method.
