Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Kiwi-sia: you're printing the pointer to the ArrayList, that's not how you print it in Java, google how to do it properly.
It's kind of frustrating how some people know what they're doing and their code is literally one line whereas I was struggling for more than three hours (not even joking) and came up with like 30 lines of barely working solution
I mean it's great that people know their sutff but it's hard to accept how out of reach they feel when you are just a beginner
On my side, the error messages look like this:
expected:<13> but was:<...>, the input is not printed. Can you post your code with a spoiler flag?Unfortunately, I am on the right kata. It's the error message that I don't understand since I do see the same type declared (ArrayList), and I certainly did not change it
I think you are not posting on the right kata. For Java the input is a list of integer pairs, declared as
ArrayList<int[]>, no string.I keep on having this kind of input in all the test errors I get (java): For input string: "[I@436a4e4b"
Weren't we supposed to get numbers with commas?
