 stream.  | 
          
        
              | CheckedOutputStream | 
              The CheckedOutputStream class is used to maintain a running checksum
 of all data written to a stream.  | 
          
        
              | CRC32 | 
              The CRC32 class is used to compute a CRC32 checksum from data provided as
 input value.  | 
          
        
              | Deflater | 
              This class compresses data using the DEFLATE algorithm (see specification).  | 
          
        
              | DeflaterInputStream | 
              An InputStream filter to compress data.  | 
          
        
              | DeflaterOutputStream | 
              This class provides an implementation of FilterOutputStream that
 compresses data using the DEFLATE algorithm.  | 
          
        
              | GZIPInputStream | 
              The GZIPInputStream class is used to read data stored in the GZIP
 format, reading and decompressing GZIP data from the underlying stream into
 its buffer.  | 
          
        
              | GZIPOutputStream | 
              The GZIPOutputStream class is used to write data to a stream in the
 GZIP storage format.  | 
          
        
              | Inflater | 
              This class decompresses data that was compressed using the DEFLATE
 algorithm (see specification).  | 
          
        
              | InflaterInputStream | 
              This class provides an implementation of FilterInputStream that
 decompresses data that was compressed using the DEFLATE algorithm
 (see specification).  | 
          
        
              | InflaterOutputStream | 
              An OutputStream filter to decompress data.  | 
          
        
              | ZipEntry | 
              An instance of ZipEntry represents an entry within a ZIP-archive.  | 
          
        
              | ZipFile | 
              This class provides random read access to a ZIP-archive file.  | 
          
        
              | ZipInputStream | 
              This class provides an implementation of FilterInputStream that
 decompresses data from an InputStream containing a ZIP archive.  | 
          
        
              | ZipOutputStream | 
              This class provides an implementation of FilterOutputStream that
 compresses data entries into a ZIP-archive output stream.  |
