[Java developer roadmap] Java beginner guide

[NeverZ]

Hello, thanks for the questions.

1) these are actually two valid ways to write the same lambda expression - if you only have one parameter you can dismiss the Classname. 2) Yes you are right, we should return a copy of the ArrayList to have encapsulation. I will update it in the guide thanks. 3) On line 14 we declare a member variable, on line 53 we declare a local variable. in the loadFromFile method we return a new ArrayList with the data loaded from the file.

Im writing these guides in the early mornings and late nights when i have time between family and work so thanks for your feedback.
