question: public static final byte [ ] unzip ( byte [ ] in ) throws IOException { ByteArrayOutputStream outStream = new ByteArrayOutputStream ( EXPECTED_COMPRESSION_RATIO * in . length ) ; GZIPInputStream inStream = new GZIPInputStream ( new ByteArrayInputStream ( in ) ) ; byte [ ] buf = new byte [ BUF_SIZE ] ; while ( true ) { int size = inStream . read ( buf ) ; if ( size <= 0 ) break ; outStream . write ( buf , 0 , size ) ; } outStream . close ( ) ; return outStream . toByteArray ( ) ; }
target:  Returns an gunzipped copy of the input array.
