I must use an existing method that is like saveAttachment(Attachment attachment) where Attachment has a File attribute.
My problem is that I'm retrieving a byte[] and I want to save it using this method. How can I have a "local" File just for saving ?
Sorry if my question is dumb, I don't know much about Files in Java.

Convert byte[] array to File using Java In order to convert a byte array to a file, we will be using a method named the getBytes() method of String class. Implementation: Convert a String into a byte array and write it in a file.
Java – How to save byte[] to a file write is the simplest solution to save byte[] to a file. // bytes = byte[] Path path = Paths. get("/path/file"); Files. write(path, bytes);
write(bytes, new File(path)); With Apache Commons: FileUtils. writeByteArrayToFile(new File(path), bytes);
File tempFile = File.createTempFile(prefix, suffix, null); FileOutputStream fos = new FileOutputStream(tempFile); fos.write(byteArray); Check out related docs:
File.createTempFile(prefix, suffix, directory);
