Java Compression Library for Handling ZIP Archives

Open Source Java API enables programmers to compress a file or directory into a ZIP archive, comparing two ZIP archives entries & so on.

zt-zip (ZeroTurnaround ZIP Library) is a simple archiving and compression library for Java that enables software developers to operate with Java archives inside their own apps. The library supports packing and unpacking directories recursively and easily iterating through ZIP entries. The library is very simple and produces efficient results when only single entries are extracted from ZIP files.

The library has included support for both basic and some advanced features, such as Compress a directory into a ZIP archive, compressing a file into a ZIP archive, adding an entry from a file or byte array to a ZIP archive, replacing a ZIP archive entry from file or from a byte array, Add or replace entries in a ZIP archive, Extract a ZIP archive, Check if an entry exists in a ZIP archive, extract an entry from a ZIP archive into a byte array, extract a ZIP archive which becomes a directory and many more.

The library is very safe to use and makes sure that no streams are left open by accident. The library also supports comparing two ZIP archives entries with different names as well as with the same name. You can also easily transform a ZIP archive entry into uppercase.
