Data scraping with jsoup and saving in txt

Hello, how are you guys? I'm trying to learn how to scrape data on my account, and since my English does not help, I'm turning 30. It's basically the following. While executing my code, he lists the athletes of the International Judo Federation, one below the other. I've found that every iteration, it picks up all of a country at a time. Then the String becomes a block with all the athletes of that country. I'd like to split up to catch one athlete at a time, but I could not. Then, when printing, it prints one underneath the other, however, when sending to txt, it does not do that, it puts everything on the same line and only jumps when it changes parents. Another thing I noticed is that he glues the last name of an athlete to the first of the next.  Example: The code is saving txt:

The Nacoes class has only two strings and their getters / setters.

Follow a piece of code from the site if someone would suggest an easier way.
