Please complete these files. There are two text files attached. Running the code should result in the creation of an output file ("PE_output.txt"). Please give full reasoning to the answer. Please also paste the full java code and please attach a screenshot of the successful program run.

Can I write a functional Java program? Is it possible to get a CS internship?

Am I a good programmer? Can someone explain what good coding style is?

How is data science related to computer science? What attributes should a good programmer have? How can I become a better programmer? What will I do after this class? How do you learn how to debug a program?

How much effort does it take to prep for a technical interview? How come I usually can't understand everything in my CS class? What do you consider the best advice for someone studying CS?
