FileInputStream without Creating an Actual File using Java

Question

I was wondering if there was any way to create a FileInputStream object from just a file object without creating an actual file on the file system? What I am attempting to do is create a file object with some information, and then upload that file somewhere else. I have no need for it to be on the local file system. I know that I could just create a temp folder and then delete it afterwards, but was wondering if it was possible to not do it that way?

In that case you should not work with any file-related classes at all. Instead, crate a byte array, which you can tread as an InputStream via ByteArrayInputStream.

Answer 2

You are probably looking for a ByteArrayInputStream or something similar.

A file input stream reads from a file on disk, that is its purpose. By the way, a File object in Java does not really represent a file, but rather the path pointing to a (potential) file on disk.
