Oracle Exam 1Z0-808 Topic 11 Question 101 Discussion

Actual exam question for Oracle's 1Z0-808 exam

Question #: 101
Topic #: 11

Given these requirements:

Bus and Boat are Vehicle type classes.

The start() and stop() methods perform common operations across the Vehicle class type.

The ride() method performs a unique operations for each type of Vehicle.

Which set of actions meets the requirements with optimized code?

A1. Create an abstract class Vehicle by defining start() and stop() methods, and declaring the ride()
abstract method.
2. Create Bus and Boat classes by inheriting the Vehicle class and overriding the ride() method.

B1. Create an interface Vehicle by defining start() and stop() methods, and declaring the ride()
abstract method.
2. Create Bus and Boat classes by implementing the Vehicle class.

C1. Create an abstract class Vehicle by declaring stop(), start(), and ride() abstract methods.
2. Create Bus and Boat classes by inheriting the Vehicle class and overriding all the methods.

D1. Create an interface Vehicle by defining default stop(), start(), and ride() methods.
2. Create Bus and Boat classes by implementing the Vehicle interface and overriding the ride()
method.

Option D is like trying to make a square wheel. You can't define default methods for the ride() method, that's just nonsense. Stick with Option A, folks!

Definitely, sticking with Option A would be the most optimized approach for this scenario.

Yeah, Option A seems like the best choice. Abstract class for common methods and overriding ride() for specific behavior.

I agree, Option D doesn't make sense. Default methods for ride() would defeat the purpose.

Option C is just overkill. Why make everything abstract when you can just use the Template Method in Option A? Developers these days, always trying to overcomplicate things.

I think option D is the way to go because it uses an interface with default methods for common operations and allows for specific implementations in subclasses.

Haha, Option B is like trying to put square pegs in round holes. Interfaces are great, but not for this use case. Option A is definitely the way to go.

Interfaces might not be the best fit here, abstract classes offer more control.

I see your point, Hoa, but I think option C is the most optimized choice as it uses an abstract class with all methods declared as abstract.

I disagree, I believe option B is better as it uses an interface which allows for more flexibility in implementing different types of vehicles.

I'm not sure why the other options are even there. Option A is clearly the most elegant and maintainable solution. I'm surprised this is even a question!

Option A is the way to go. Defining the common methods in an abstract class and letting the subclasses handle the unique operations is a classic example of the Template Method pattern.
