Reading multiple charset based files

Question

Hi !
I have a strange tricky problem :-). I have 6 different HTMLs with 6 different character set encodings (ShiftJIS, EUCJP, EUCKR, UTF-8 etc.,). I want to read them and copy over to another directory. I do not know the encoding before hand(there can be any number of files with any encoding). I used the following code but it just "bombs"? Any clue how I should do this?

<pre>
public class TestWriter {
     public static void main(String[] args) {
          try {
               InputStreamReader fin = new InputStreamReader(new FileInputStream(args[0]), "Shift-JIS");
               OutputStreamWriter fout = new OutputStreamWriter(new FileOutputStream(args[0]+"_1"), "Shift-JIS");
               int readIn = fin.read();
               while (readIn != -1)
                    fout.write(readIn);
                    readIn = fin.read();
               fout.close();
               fin.close();
          } catch(Exception e) {
               e.printStackTrace();
</pre>

My guess is that the file you are reading is not SJIS and causing the program to throw an exception.
There is no easy way to do this but it is doable with some effort.
