Convert file into byteArray

Question

Hi, I have a file named programa.class and I would like to copy its byte content into a byte array, so I can send it later through the COM1 port. Can someone give me an example of how can this be done? Thanks in advance.

for your enjoyment ...
  try {
  String inpName = "dime.zip";
  File inpFile = new File(inpName);
  long lcount = inpFile.length();
  int icount = (int) lcount;
  InputStream inp = new FileInputStream(inpFile);
  int acount = inp.available();
  if (icount != acount) {
    System.out.println("all bytes not available");
    return;
  byte[] iobytes = new byte[acount];
  int ic = 0;
  while (ic < acount) {
    ic += inp.read(iobytes, ic, acount - ic);
  inp.close();
  } catch (IOException ioe) {System.out.println(ioe);}
