In my app I have a Linked List (type List),
every time the user starts the app I want to restore the list from the Internal Storage (if there is a saved file on the Internal Storage) or create a new list (to be saved later on).
How can I use the read/write functions (on FileInputStream/FileOutputStream) to do it ?
