    relatively easy question, just having a brain cramp. I have a 15 line .txt file I'm reading, and I'm trying to figure out how to only print out one specified line.

    Read each line into a String array of 15 indexes and print the specific index required.

    How are you recognizing the line? By position, or by content?

    Yep. You're going to have to come up with a way to differentiate lines.

    Assuming there's no monkey business, that's pretty simple. Open the file. Read lines until you get to the one you want. That's your line.
