| Adler32 | 
          The Adler-32 class is used to compute the Adler32 checksum from a set
 of data. 
          
    
         | 
      
| CheckedInputStream | 
          The CheckedInputStream class is used to maintain a checksum at the
 same time as the data, on which the checksum is computed, is read from a
 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 entry within a zip file. | 
| ZipFile | This class provides random read access to a zip file. | 
| ZipInputStream | Used to read (decompress) the data from zip files. | 
| ZipOutputStream | Used to write (compress) data into zip files. | 
| DataFormatException | 
          DataFormatException is used to indicate an error in the format of a
 particular data stream which is to be uncompressed. 
          
    
         | 
      
| ZipException | 
          This runtime exception is thrown by ZipFile and ZipInputStream when the file or stream is not a valid zip file. 
          
    
         | 
      
| ZipError | Thrown when an unrecoverable zip error has occurred. |
