TAILIEUCHUNG - Lecture Object Oriented Programing - Chapter 14: Files and streams

In chapter 14 you will learn: To create, read, write and update files; to use class File to retrieve information about files and directories; the Java input/output stream class hierarchy; the differences between text files and binary files; sequential-access and random-access file processing; to use classes Scanner and Formatter to process text files; to use the FileInputStream and FileOutputStream classes. | 14 Files and Streams I can only assume that a “Do Not File” document is filed in a “Do Not File” file. Senator Frank Church Senate Intelligence Subcommittee Hearing, 1975 Consciousness does not appear to itself chopped up in bits. A “river” or a “stream” are the metaphors by which it is most naturally described. William James I read part of it all the way through. Samuel Goldwyn A great memory does not make a philosopher, any more than a dictionary can be called grammar.
