Interface Summary
Checksum An interface representing a data checksum.
 

Class Summary
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.
CRC32 A class that can be used to compute the CRC-32 of a data stream.
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.
ZipFile This class is used to read entries from a zip file.
ZipInputStream This class implements an input stream filter for reading files in the ZIP file format.
ZipOutputStream This class implements an output stream filter for writing files in the ZIP file format.
 

Exception Summary
DataFormatException Signals that a data format error has occurred.
ZipException Signals that a Zip exception of some sort has occurred.
 

Error Summary
ZipError Signals that an unrecoverable error has occurred.
 

Package java.util.zip Description

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 and Adler-32 checksums of arbitrary input streams.
