In this part of my Java Video Tutorial, I completely cover how to both write to and read character streams from files.

I explain all of the following: PrintWriter, BufferedWriter, FileWriter, BufferedReader, FileReader, common file exceptions and much more.

    How do I get the line numbers out of the code, when I copy and paste it?

    You spend too much times typing and repeating what you are typing on the screen, but you neglect to explain what are those codes, method, objects are for.

    Thank You So much. This was really helpful. Although, you really need to watch twice and read the code to get it, ITS TOTALLY WORTH IT!

    I've always had issues with files in programming and I was getting discouraged when I saw persons saying the video was hard to understand but then I watched and it really opened my eyes to the use of files. Thanks so much!

    Hi Derek,
    i tried using the code PrintWriter infoWrite = new PrintWriter((listOfNames)); instead of using BufferedWriter and FileWriter, and i was able to write into the file. Could you please explain why BufferedWriter and FileWriter were necessary here? Thanks in advance!

    "Well, hello Internet….

    …Otherwise, till next time…"

    Brilliant as usual.

    Folks, if you're having trouble following just pause and go back, that's the beauty of it.
    Also helpful to have the full commented code (link in the description) beside you as a reference.
