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.
