    Default Need help! Encoding from a file.

    Been working on this for a while now..

    The idea is to "encode" a text file, then pass it on to the console and also a new file. Such as taking input from a text file that reads "Hello" and convert it for output reading "ifmmp". Each character value gets 1 added to it. Also each line of input should transfer to a "coded" line of output, then go to the next line.

    The closest I can get to it is either just displaying the first line or if I change it to 'println' it displays everything, but as single characters per line.

    Any help would be much appreciated!

    Java Code:
            char sNew;
            String sOld = fin.readLine();
            while ((sOld = fin.readLine()) != null)
              for (int i = 0; i < sOld.length(); i++)
                     if (i < sOld.length())
                     sNew = (char)(sOld.charAt(i) + 1);
              } //for
            } //while

    Have a look at the StringBuilder class; it can collect your sNew characters and convert the entire char sequence to a String at the end.

    kind regards,
