Consider the following class hierarchy:
Public class Vehicle
{
Private String type;
Public Vehicle(String type)
{
This.type = type;
}
Public String displayInfo()
{
Return type;
}
}
Public class LandVehicle extends Vehicle
{
Public LandVehicle(String type)
{
Super(type);
}
}
Public class Auto extends LandVehicle
{
Public Auto(String type)
{
_________;
}
}
Complete the code in the Auto class constructor to store the type data.
A) super(type);
B) super(super(type));
C) super.super(type);
D) This cannot be done unless the Auto declares an instance variable named type.

Question

Quizplus · Accepted Answer

The constructor of Auto should call the constructor of its immediate parent class which is LandVehicle by using the super keyword. The LandVehicle constructor, in turn, should call the constructor of the Vehicle class using super(type) to pass the type data down the hierarchy. Therefore, the correct code in the Auto class constructor is super(type).
