title: How to store a list of objects to memory for later use
body: <p>I am trying to write a program which will help manage some data. So far, the user can create a new file using a "New File" Dialogue. After the user has entered some parameters, I create a new instance of a "File" class. My questions now is: How can I store multiple files (like tabs) in memory. I was thinking about using some sort of <em>ArrayList</em> as a variable in an "Application" class. What would be an ideal approch here?</p>
