Please, format your code when you create a post. To do that, highlight your lines of code and press ctrl+o. Ensure there is an empty line above and below the code. Here next I present a solution for you to consider:

@kfrajer -- if you would, could you say something very briefly about what the mistake was, and why the solution works? Code-only solutions tend to be hard to understand for some beginners experiencing the same problem.
I agree with you @jeremydouglass . However it is hard to provide full detail as initial code was not formatted. From my version of the code, I did a small modification to the controlEvent() function. The problem was that data was not been appended from the input to the output textField. I remove the culprit line 47 and modified line 46 so it added a line separator. Then I added line 50 to 56 to reset/clear the output text field and then join all string objects under a single String variable, fullStr before setting it in the the textField output.

For jeremydouglas: I tried a lot of solutions but the magic is in the:
There is a really god solution.``
