Need help! Encoding from a file.

Been working on this for a while now.. :s:

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!

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);
               
                System.out.print(sNew);
                fout.print(sNew);
                }
          } //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,
