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.
It's not in my code. I ran the sample tests and everything is OK, but with the attempt button I got the error:
./src/test/java/EncodeTest.java:10: error: incompatible types: Leetspeak cannot be converted to Encoder
myEncoder = new Leetspeak();
Leetspeak cannot be converted to Encoder
myEncoder = new Leetspeak();
^
Why I´m getting this?
