Why is this code not working

Question

class Main {
public static void main(String[] args) {

Vehicle vehicle = new Vehicle();
Vehicle electric = new ElVehicle();
Vehicle hybrid = new HybridVehicle();

//calls
vehicle.start();
vehicle.resource();
electric.start();
electric.resource();
hybrid.start();
hybrid.resource();
}
}
class Vehicle{
public void start(){
System.out.println("Starting");
}
public void resource(){
System.out.println("I use petrol");
}
}

class ElVehicle extends Vehicle{
/*reimplement resource() method
to output "I use electricity"*/
public void resource(){
System.out.println("I use electricity");
}

class HybridVehicle extends Vehicle{
/*reimplement resource() method
to output "I use both petrol and electricity"*/
public void resource(){
System.out.println("I use both petrol and electricity");
}

Answer 1

People more readily test your code when you LINK it instead of pasting it into the description box.

Answer 3

You forgot to put } closing braces at the end of resource() method in ElVehicle and HybridVehicle class.

Make sure that all your braces are in pairs!
