Protected Variables

At 14:11 he makes the variables protected. Why not just use getTitle()?

For future projects I believe, or just for variation in ways, I guess that in some future projects there will be no 'get' methods for some variables, and we'll need to make use of them inside the package. hope i've helped :)

Protected is more than package. So in this example I would rather use package than protected, couse files are in same package. Protected give access to this class fields or methods for objects inside other packages but only if they inherit from that class. Less is better.
