Answer the following questions based on the following classes:

public interface Washable

{

void wash();

}

public abstract class Vehicle implements Washable

{

private String name;

public String getName()

{

return name;

}

}

public class Car extends Vehicle

{

@Override

public void wash()

{

// some super special code here

}

void boolean premiumGas()

{

// more code

}

)

What is the name of the interface?

Washable

Is the interface a functional interface? Why or why not?

Yes, any interface containing only one abstract method is known as a functional interface.

What is the name of the superclass?

Vehicle

What is the name of the subclass?

Car

Why did we have to put abstract on the Vehicle class?

Is Car also abstract? Why or why not?

Declare a variable of type Vehicle, but assign it an object of type Car

If you have the variable: Vehicle v, but you know it hold a Car reference, write a line that will print the value returned by calling premiumGas
