Is there any way to convert Java String to a byte    not the boxed Byte      In trying this   System out println response split   r n r n   1    System out println            System out println response split   r n r n   1  getBytes   toString       and I m getting separate outputs  Unable to display 1st output as it is a gzip string    lt A Gzip String gt          B 38ee9f13   The second is an address  Is there anything I m doing wrong  I need the result in a byte   to feed it to gzip decompressor  which is as follows   String decompressGZIP byte   gzip  throws IOException       java util zip Inflater inf   new java util zip Inflater        java io ByteArrayInputStream bytein   new java io ByteArrayInputStream gzip       java util zip GZIPInputStream gzin   new java util zip GZIPInputStream bytein       java io ByteArrayOutputStream byteout   new java io ByteArrayOutputStream        int res   0      byte buf     new byte 1024       while  res  gt   0            res   gzin read buf  0  buf length           if  res  gt  0                byteout write buf  0  res                       byte uncompressed     byteout toByteArray        return  uncompressed toString

I know I m a little late tothe party but thisworks pretty neat  our professor gave it to us   public static byte   asBytes  String s                                  String tmp             byte   b   new byte s length     2              int i             for  i   0  i  lt  s length     2  i                   tmp   s substring i   2  i   2   2                b i     byte  Integer parseInt tmp  16   amp  0xff                           return b                                               return bytes

It is not necessary to change java as a String parameter  You have to change the c code to receive a String without a pointer and in its code   Bool DmgrGetVersion  String szVersion    Char NewszVersion  200   Strcpy  NewszVersion  szVersion t str       t str    applies to builder c    2010

The object your method decompressGZIP   needs is a byte     So the basic  technical answer to the question you have asked is   byte   b   string getBytes    byte   b   string getBytes Charset forName  UTF-8     byte   b   string getBytes StandardCharsets UTF 8      Java 7  only     However the problem you appear to be wrestling with is that this doesn t display very well  Calling toString   will just give you the default Object toString   which is the class name   memory address  In your result  B 38ee9f13  the  B means byte   and 38ee9f13 is the memory address  separated by an     For display purposes you can use   Arrays toString bytes     But this will just display as a sequence of comma-separated integers  which may or may not be what you want   To get a readable String back from a byte    use   String string   new String byte   bytes  Charset charset       The reason the Charset version is favoured  is that all String objects in Java are stored internally as UTF-16  When converting to a byte   you will get a different breakdown of bytes for the given glyphs of that String  depending upon the chosen charset
