No idea how to proceed. Can anybody point to some more background information in regards to calling one method in another method wile iterating over a HashMap? I'm really stuck on this topic and even though I keep rereading the articles I can't find a way to solve these task. Really I actually do not know where to begin. If someone can send me a link with a better explanation of these topics I would very much appreciate it. I also hope that codegym will be better at explaining other complicated concepts because I'm rather disappointed at this moment and I'm making too little progress in the last few days. Other learners feel the same?
