Examples of org.apache.commons.compress.archivers.zip.ZipArchiveInputStream

org.apache.commons.compress.archivers.zip.ZipArchiveInputStream
Implements an input stream that can read Zip archives.
Note that {@link ZipArchiveEntry#getSize()} may return -1 if theDEFLATE algorithm is used, as the size information is not available from the header.

The {@link ZipFile} class is preferred when reading from files.
As of Apache Commons Compress it transparently supports Zip64 extensions and thus individual entries and archives larger than 4 GB or with more than 65536 entries.
@see ZipFile @NotThreadSafe
