Package java.util.zip

package java.util.zip
Provides classes for reading and writing the standard ZIP and GZIP file formats. Also includes classes for compressing and decompressing data using the DEFLATE compression algorithm, which is used by the ZIP and GZIP file formats. Additionally, there are utility classes for computing the CRC-32, CRC-32C and Adler-32 checksums of arbitrary input streams.

Class Description
Adler32
A class that can be used to compute the Adler-32 checksum of a data stream.
CheckedInputStream
An input stream that also maintains a checksum of the data being read.
CheckedOutputStream
An output stream that also maintains a checksum of the data being written.
Checksum
An interface representing a data checksum.
CRC32
A class that can be used to compute the CRC-32 of a data stream.
CRC32C
A class that can be used to compute the CRC-32C of a data stream.
DataFormatException
Signals that a data format error has occurred.
Deflater
This class provides support for general purpose compression using the popular ZLIB compression library.
DeflaterInputStream
Implements an input stream filter for compressing data in the "deflate" compression format.
DeflaterOutputStream
This class implements an output stream filter for compressing data in the "deflate" compression format.
GZIPInputStream
This class implements a stream filter for reading compressed data in the GZIP file format.
GZIPOutputStream
This class implements a stream filter for writing compressed data in the GZIP file format.
Inflater
This class provides support for general purpose decompression using the popular ZLIB compression library.
InflaterInputStream
This class implements a stream filter for uncompressing data in the "deflate" compression format.
InflaterOutputStream
Implements an output stream filter for uncompressing data stored in the "deflate" compression format.
ZipEntry
This class is used to represent a ZIP file entry.
ZipError
Signals that an unrecoverable error has occurred.
ZipException
Signals that a Zip exception of some sort has occurred.
ZipFile
This class is used to read entries from a zip file.
ZipInputStream
An input stream for reading compressed and uncompressed ZIP file entries from a stream of bytes in the ZIP file format.
ZipOutputStream
This class implements an output stream filter for writing files in the ZIP file format.
