Name

ZipFile

Synopsis

This class reads the contents of ZIP files. It uses a random-access file internally so that the entries of the ZIP file do not have to be read sequentially, as they do with the ZipInputStream class. A ZipFile object can be created by specifying the ZIP file to be read either as a String filename or as a File object. In Java 1.3, temporary ZIP files can be marked for automatic deletion when they are closed. To take advantage of this feature, pass ZipFile.OPEN_READ|ZipFile.OPEN_DELETE as the mode argument to the ZipFile( ) constructor.

Once a ZipFile is created, the getEntry( ) method returns a ZipEntry object for a named entry, and the entries( ) method returns an Enumeration object that allows you to loop through all the ZipEntry objects for the file. To read the contents of a specific ZipEntry within the ZIP file, pass the ZipEntry to getInputStream( ); this returns an InputStream object from which you can read the entry’s contents.
