Python Programming with the Java™ Class Libraries: A Tutorial for Building Web and Enterprise Applications with Jython

Summary

Streams are Java's way to support I/O. They can represent a file, a network connection, or access to a Web site. In this chapter, we dealt mostly with file streams because they're easy to work with and demonstrate stream fundamentals. Learning to deal with Java streams is essential for learning to use the Java APIs.

The Java File class allows access to a file's attributes: Is the file read-only? Is it a directory? and so forth. It also allows the creation of directories.
