Questions tagged [zipoutputstream]

ZipOutputStream is used to write ZipEntrys to the underlying stream. Output from ZipOutputStream can be read using ZipFile or ZipInputStream.

A ZipOutputStream is a mechanism for writing data to a stream in a zip-compressed format. A stream is usually comprised of data to write to a local file, or data being transmitted to a remote server over a network protocol such as HTTP or FTP. As the data is given to the ZipOutputStream, it is compressed, and then transmitted to the stream.
