a research paper that will be published. The class should have instance
variables to store the author's name, title of the paper, and the date of
submission. Add a constructor to the class that allows the user of the
class to set all instance variables. Also add a method, displayDetails,
that outputs all the instance variables, and another method called
getSubmission Details that returns the title of the paper, with the first
letter of each word capitalized. Test your class from the main method.
