This class is a subclass of
InflaterInputStream that reads the entries of a
ZIP file in sequential order. Create a
ZipInputStream by specifying the
InputStream from which it is to read the contents
of the ZIP file. Once the ZipInputStream is
created, you can use getNextEntry( ) to begin
reading data from the next entry in the ZIP file. This method must be
called before read( ) is called to begin reading
the first entry. getNextEnTRy( ) returns a
ZipEntry object that describes the entry being
read, or null when there are no more entries to be
read from the ZIP file.
The read( ) methods of
ZipInputStream read until the end of the current
entry and then return -1, indicating that there is no more data to
read. To continue with the next entry in the ZIP file, you must call
getNextEntry( ) again. Similarly, the
skip( )
method only skips bytes within the current entry.
closeEntry( ) can be called to skip the remaining
data in the current entry, but it is usually easier simply to call
getNextEnTRy( ) to begin the next entry.
