Insert the missing code in the following code fragment. This fragment is intended to call the Vehicle class's method. public class Vehicle { . . . public void setVehicleClass(double numberAxles) { . . . } } public class Motorcycle extends Vehicle { . . . public Motorcycle() { ; } }

The answer is D.

Explanation:

The question is incomplete, here is the full question;

Insert the missing code in the following code fragment. This fragment is intended to call the Vehicle class's method.

public class Vehicle

{

. . .

public void setVehicleClass(double numberAxles)

{

. . .

}

}

public class Motorcycle extends Vehicle

{

. . .

public Motorcycle()

{

;

}

}

a) Motorcyle.setVehicleClass(2.0);

b) Vehicle.setVehicleClass(2.0);

c) this.setVehicleClass(2.0);

d) setVehicleClass(2.0);

According to the information and the code snippet given in the question, the correct answer to fill in the blank should be D,  setVehicleClass(2.0); because it is in the Motorcycle class which "extends" vehicle meaning that it's a subclass.

I hope this answer helps.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
