Does java provide any support for MD5

Question

I want to develop a program which in vc++ should produce a message digest using MD5 for a file and i want to check this file and hashcode generated for its equality . Does Java provide MD5 algo for it.
ie what i have to do
file + MD5 algo (Implemented in vc++) = Message Digest 1
Will Message Digest 1 == Message Digest Generated by Java MD5 algo + file
Thanks

Answer 1

Here's a simple example of creating an MD5 in java:
    public byte[] createMD5( final InputStream data )
        throws NoSuchAlgorithmException, IOException
        MessageDigest md5 = MessageDigest.getInstance( "MD5" );
        final byte buf[] = new byte[ 8192 ];
        int bytes = 0;
        while ( ( bytes = data.read( buf ) ) != -1 )
            md5.update( buf, 0, bytes );
        return md5.digest();
    }
