Answer 1

That simply gets the File as a byte[]. I use the following method
public static byte[] getBytesFromFile(File file) throws IOException {
          InputStream is = new FileInputStream(file);
          long length = file.length();
          // You cannot create an array using a long type.
          // It needs to be an int type.
          // Before converting to an int type, check
          // to ensure that file is not larger than Integer.MAX_VALUE.
          if (length > Integer.MAX_VALUE) {
               // File is too large
          // Create the byte array to hold the data
          byte[] bytes = new byte[(int) length];
          // Read in the bytes
          int offset = 0;
          int numRead = 0;
          while (offset < bytes.length && (numRead = is.read(bytes, offset, bytes.length - offset)) >= 0) {
               offset += numRead;
          // Ensure all the bytes have been read in
          if (offset < bytes.length) {
               throw new IOException("Could not completely read file " + file.getName());
          // Close the input stream and return bytes
          is.close();
          return bytes;
     }
