Decoding a file of bytes (The bad way)

• public static int[] decodeFile

• • • • • • • • • ( String fileName, int n) throws IOException{
  • FileReader fileIn= new FileReader(fileName);
  • int currByte;
  • for(int i = 1; i < n; i++){
  • • currByte = fileIn.read();
    • System.out.println(Decoder.decode((byte)currByte));
  • }
  • fileIn.close();
  • }
  • What is bad here?
