question: public int inflateByteArray ( int numberOfBytes , byte [ ] source , byte [ ] target ) throws DataFormatException { if ( numberOfBytes == 0 ) return 0 ; if ( numberOfBytes < 0 ) { System . arraycopy ( source , 0 , target , 0 , source . length ) ; return Math . abs ( numberOfBytes ) ; } inflater . setInput ( source , 0 , numberOfBytes ) ; int resultLength = inflater . inflate ( target ) ; inflater . reset ( ) ; return resultLength ; }
target:  decompresses an array of bytes to bytes
