Module java.base

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.

    ClassDescription
    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.
    CRC32C
    A class that can be used to compute the CRC-32C 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
