Java SE 8 Programmer II — Question 164

Given:
class FuelNotAvailException extends Exception { }
class Vehicle {
void ride() throws FuelNotAvailException { //line n1
System.out.println("Happy Journey!");
}
}
class SolarVehicle extends Vehicle {
public void ride () throws Exception { //line n2
super ride ();
}
}
and the code fragment:
public static void main (String[] args) throws FuelNotAvailException, Exception {
Vehicle v = new SolarVehicle ();
v.ride();
}
Which modification enables the code fragment to print Happy Journey!?

Answer options

• A. Replace line n1 with public void ride() throws FuelNotAvailException {
• B. Replace line n1 with protected void ride() throws Exception {
• C. Replace line n2 with void ride() throws Exception {
• D. Replace line n2 with private void ride() throws FuelNotAvailException {

Correct answer: B

Explanation

The correct option B allows the ride() method in SolarVehicle to properly override the ride() method in Vehicle while maintaining the correct exception handling. The other options either change the access modifier incorrectly or do not align with the exception types, leading to potential compilation errors.
