Join David Gassner for an in-depth discussion in this video Using buffered streams, part of Java Advanced Training.
When you're dealing with large text files, it's a good idea to wrap your FileReaders…and FileWriters inside classes that will buffer the operations.…Buffering the read and write operations is a good way of automatically managing memory…so that you're efficiently putting content into memory and taking it out.…It's a pretty simple operation.…You can use the buffered reader and buffered writer classes wrapped around any instance…of a reader or writer such as FileReader and FileWriter.…
I'll demonstrate this in the class BufferedStreams.…In the main application, I'm currently using instances of the FileReader and FileWriter,…but this time I'm going to be reading and writing a much larger file.…Instead of a simple text file with just a paragraph of text, I'm going to read the entire…content of the play Hamlet in XML.…This file that I'll be reading has been provided as a public domain service, and again,…it's the entire content of a very long play.…
You can do the same sort of demonstration with any long text file.…
