Java / Remote Control Competition

Exercism Bugs & Feature Requests

Hello i’m reporting this issue, already asked about on discord:

Seems to be an error in the test script and/or description of the exercise

2

It might be helpful to supply details. Some people might not be on Discord :slightly_smiling_face:

is the exercise code itself expected to create prc1 and prc2 correctly and pass them to getRankedCars?

public static List<ProductionRemoteControlCar> getRankedCars(ProductionRemoteControlCar prc1, ProductionRemoteControlCar prc2) {

because it gives me this error:

More specifically, the stubs set up a getRankedCars() function which takes two Car objects. The unit tests pass in a list of Car objects. The stubs and unit tests should be in sync with what the function signature is.

+cc @andrerfcsantos @SleeplessByte Should I send a PR for this?

That would be appreciated. Thanks!

@andrerfcsantos Change TestTrack.getRankedCars stub to take a list of cars, consistent with the unit tests by IsaacG · Pull Request #2337 · exercism/java · GitHub

This should now be fixed.
