Let's breakdown the statement: private Story mStory = new Story();

  • "private": This object will only be accessible by objects of this class (in this case, StoryActivity).
  • "Story": This member variable is of type Story.
  • "mStory": This is the name of the variable so we can refer to it later.
  • "new Story()": This calls the constructor to create an instance of the object.
  • "=": Take the object instance from "new Story()" and store it in the mStory variable.
