title: Using an object.function(argument)
body: <p>So, in one of my class assignments, I have to create a function for a book that prints the book title with a prefix.</p>
  
  <p>But since the book isn't an argument to this function, I don't see how to "access" the title. If it were an argument, for example, to a function <code>print(prefix, book)</code> I could call <code>system.out.print(prefix + book)</code>, but since it comes before the function I have no idea how to do it (I'm a beginner programmer). </p>
