I feel like this kinda defeats the point of the challenge

JavaScript translation, had fun with this Kata

The core object of the kata, PhoneNumber, is defined by user code (and defined in a way that clearly shows lack of basic Java knowledge), which is very wrong in many levels. It should be provided by the kata via Preloaded.

The order of elements in the merged list does not matter

Then a proper type should be used, like Set.

Can someone explain me this one?

"rather straight forward"

I was more asking for the thought process which was interesting me

Same thing

Where does the %3600/60 come from? Isn't /60%60 rather straight forward?

I'm very new to Java, but man it's weird that I can't instantiate a List, but I am working with two List objects that must have been instantiated at some point? Maybe it's just me...

And yes, it's also weird to fail the example tests and then pass the random+ tests.

Did you learn SQL ? :)

It is a builtin XOR operator

It's still giving me issues.
