And the Rest . . .

In addition to the classes and interfaces discussed in this lesson, java.io contains the following classes and interfaces:

File

Represents a file on the native file system. You can create a File object for a file on the native file system and then query the object for information about that file (such as its full pathname).

FileDescriptor

Represents a file handle (or descriptor) to an open file or an open socket. You will not typically use this class.

StreamTokenizer

Breaks the contents of a stream into tokens. Tokens are the smallest unit recognized by a text-parsing algorithm (such as words, symbols, and so on). A StreamTokenizer object can be used to parse any text file. For example, you could use it to parse a Java source file into variable names, operators, and so on, or to parse an HTML file into HTML tags.

FilenameFilter

Used by the list method in the File class to determine which files in a directory to list. The FilenameFilter accepts or rejects files based on their names. You could use FilenameFilter to implement simple regular expression style file search patterns such as foo*.

You also can find some other input and output streams in the java.util.zip package, including these:

CheckedInputStream and CheckedOutputStream

An input and output stream pair that maintains a checksum as the data is being read or written.

DeflaterOutputStreamand InflaterInputStream

Compresses or uncompresses the data as it is being read or written.

GZIPInputStream and GZIPOutputStream

Reads and writes compressed data in the GZIP format.

ZipInputStream and ZipOutputStream

Reads and writes compressed data in the ZIP format.
