Question about the task Take your turn!
Java Core, Level 6, Lesson 13
Resolved
Here's a tip: you can add a class wide String variable in the class Read3Strings They show you where you should add your code, and normally if you code outside of that, this marks the task incorrect. In this case, I couldn't see how I can print a string from one function (the RUN method) in another method (printResult) if it wasn't visible to the whole class.
