Class ZipFile

src/gnu/zip/ZipFile.java:64–844

This class represents a Zip archive. You can ask for the contained entries, or get an input stream for a file entry. The entry is automatically decompressed. This class is thread safe: You can open input streams for arbitrary entries in different threads. @author Jochen Hoenicke @author Artur B
