        FileOutputStream fout = new FileOutputStream(strvin);
        while(true)
        {
         byte b=(byte)fin.read();
         fout.write(b);
         System.out.print(b);
        }
        }
        catch(EOFException ef){
                System.out.println("END OF FILE "+ef.getMessage());
