I have a large text file that I need open and scroll through. In other words is like opening a document with 200,000 lines of text or so.
Since the file is rather long, how do I open the file in a way that I only have in memory a part of it and, when I scroll up or down, the file is displayed accordingly.

Any examples, code, articles, etc. would be great.
 
It is sorta covered in the JavaRanch Style Guide.
