This package contains classes for compressing and decompressing data in
ZIP and GZIP file formats.

Interfaces
Checksum |
Holds information about a checksum which was computed with the methods
implementing a checksum algorithm. |
Classes
Adler32 |
The Adler-32 class is used to compute the Adler32 checksum from a set
of data. |
CheckedInputStream |
The CheckedInputStream class is used to maintain a checksum at the
same time as the data, on which the checksum is computed, is read from a
stream. |
CheckedOutputStream |
The CheckedOutputStream class is used to maintain a running checksum
of all data written to a stream. |
CRC32 |
The CRC32 class is used to compute a CRC32 checksum from data provided as
input value. |
Deflater |
This class compresses data using the DEFLATE algorithm (see specification). |
DeflaterOutputStream |
This class provides an implementation of FilterOutputStream that
compresses data using the DEFLATE algorithm. |
GZIPInputStream |
The GZIPInputStream class is used to read data stored in the GZIP
format, reading and decompressing GZIP data from the underlying stream into
its buffer. |
GZIPOutputStream |
The GZIPOutputStream class is used to write data to a stream in the
GZIP storage format. |
Inflater |
This class uncompresses data that was compressed using the DEFLATE
algorithm (see specification). |
InflaterInputStream |
This class provides an implementation of FilterInputStream that
uncompresses data that was compressed using the DEFLATE algorithm
(see specification). |
ZipEntry |
An instance of ZipEntry represents an entry within a ZIP-archive. |
ZipFile |
This class provides random read access to a ZIP-archive file. |
ZipInputStream |
This class provides an implementation of FilterInputStream that
uncompresses data from a ZIP-archive input stream. |
ZipOutputStream |
This class provides an implementation of FilterOutputStream that
compresses data entries into a ZIP-archive output stream. |
Exceptions
DataFormatException |
DataFormatException is used to indicate an error in the format of a
particular data stream which is to be uncompressed. |
ZipException |
This runtime exception is thrown by ZipFile and ZipInputStream when the file or stream is not a valid ZIP file. |
