Pinned topic byte arrays vs string arrays

‏2011-04-13T17:01:08Z |
Hello all, I'm new to Java programming and I'm trying to get a clear understanding regarding byte arrays and string arrays.
I have to read from a simple text file a set of ASCII display characters (400 bytes in length) and then send this ASCII data to a z/Series CICS TS 4.1 region for processing via an APPC/LU6.2 connection.

I'm going to use the FileInputStream and FileOutputStream functionality.
and the int read(byte[] Rqst_Record, 0, 400) (where Rqst_record is defined
as a byte array)

The ascii display data will be converted to EBCDIC before it is sent.

I want to "move" the contents of the byte array to a string array then convert it to EBCDIC.

When I receive a "response" from the CICS region, I need to perform this set
of operations in reverse..i.e. convert the string from EBCDIC to ASCII, then
move the data from the string array into a byte array and then written out
to a response file (again it is all displayable text)

Any ideas on how best to do this would be greatly appreciated.

Thanks

Guy

    Byte Array is much better than String Array. Data bandwidth will be very high when going for String Array rather than byteArray
