Package org.apache.commons.io
This package defines utility classes for working with streams, readers,
writers and files.
CopyUtils | This class provides static utility methods for buffered
copying between sources (InputStream , Reader ,
String and byte[] ) and destinations
(OutputStream , Writer , String and
byte[] ). |
EndianUtils | Utility code for dealing with different endian systems. |
FileCleaner | Keeps track of files awaiting deletion, and deletes them when an associated
marker object is reclaimed by the garbage collector. |
FileCleaner.Tracker | Inner class which acts as the reference for a file pending deletion. |
FilenameUtils | General filename and filepath manipulation utilities. |
FileSystemUtils | General File System utilities. |
FileUtils | General file manipulation utilities. |
HexDump | Dumps data in hexadecimal format. |
IOUtils | General IO stream manipulation utilities. |

This package defines utility classes for working with streams, readers,
writers and files. The most commonly used classes are described here:
IOUtils is the most frequently used class.
It provides operations to read, write, copy and close streams.
FileUtils provides operations based around the JDK File class.
These include reading, writing, copying, comparing and deleting.
FilenameUtils provides utilities based on filenames.
This utility class manipulates filenames without using File objects.
It aims to simplify the transition between Windows and Unix.
Before using this class however, you should consider whether you should
be using File objects.
FileSystemUtils allows access to the filing system in ways the JDK
does not support. At present this allows you to get the free space on a drive.
EndianUtils swaps data between Big-Endian and Little-Endian formats.
