Java casting resulting in run-time error instead of compilation error

Question

The following code snippet will result in a run-time:

class Vehicle {
    public void printSound() {
        System.out.print(\"vehicle\");
    }
}

class Ca         


        

Answer 1

No. v is a Vehicle and it might be possible to cast it to Bike. It's not the compiler's job to figure out the actual runtime types of every object (especially because sometimes that's impossible).
