input byte 互轉

private byte[] InputStreamToByte(InputStream is) throws IOException {
   ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
   int ch;
   while ((ch = is.read()) != -1) {
    bytestream.write(ch);
   }
   byte imgdata[] = bytestream.toByteArray();
   bytestream.close();
   return imgdata;
  }

 

byte[]轉InputStream

 

Java代碼  

byte[] data;
InputStream is = new ByteArrayInputStream(data);
