I would like to know that if java/scala has the “string object that could act as file” as StringIO in python ? I figure that it would be better than writing and reading alot of temporary file. I prefer scala but java one should be fine too.

    It depends on how this is being used. You see, while you do stuff with a file in Python, you don’t do anything with a File in Java! Well, aside from tasks like checking permission, creating, etc.

    All I/O in Java and Scala is based on one of two concepts:

    • InputStream and OutputStream
    • Reader and Writer

    What you do is create one of these classes passing a File as parameter. So, if whatever API you are using is intent on receiving a File, you can’t do anything about it. However, APIs will usually take one of the above classes, not a File, and all of them have a string-version available.

    As for Scala, there’s also scala.io.Stream, for which you can also create one based on a String.
