Thanks for tackling one of the harder issues and congrats on coming up with a working solutions. I really like the way you thought about the problem and commented the code; I think you're on the right track. For our Eclipse Collections Katas, we want our solutions to use the rich APIs provided by the Eclipse Collections (EC) library in their solutions. I added some comments about how to transform your solution in a more EC way.

Uncomment the Tag for the solutions module too. We set up the project so this tag is needed for our builds to run.

One of the design goals of Eclipse Collections is to provide functional and fluent APIs to process and use the collections that it provides. There are many built-in methods for MutableCharBags (especially methods to help with iteration) that you can leverage instead of writing a for-loop (hint: collectWithIndex and injectIntoWithIndex). This makes the code more readable and abstracts away many of the complexities of the code. We encourage contributors of our EC katas to use these methods in their solution. So try to solve this without using a for-loop or while-loop :)

Seems like you're finding the characters that are different between the guessBag and hiddenBag and storing them into one bag. Perhaps you can just use one of the iterators built-in the CharAdapter to build a single bag to keep track of the differences. You can add to the bag when the characters are present

Use collections provided by Eclipse Collections!
Add implementation to WordleEC.guess(String guess) for wordle-kata-solutions module #291
