In addition to the classes and interfaces discussed in this lesson,java.io
contains the following classes and interfaces:You also can find some other input and output streams in the
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. TheFilenameFilter
accepts or rejects files based on their names. You could useFilenameFilter
to implement simple regular expression style file search patterns such asfoo*
.java.util.zip
package, including these:
CheckedInputStream
andCheckedOutputStream
- An input and output stream pair that maintains a checksum as the data is being read or written.
DeflaterOutputStream
andInflaterInputStream
- Compresses or uncompresses the data as it is being read or written.
GZIPInputStream
andGZIPOutputStream
- Reads and writes compressed data in the GZIP format.
ZipInputStream
andZipOutputStream
- Reads and writes compressed data in the ZIP format.
