Writing stub methods

For this lab, you will write a test class, and method stubs, but not correctly-implement the methods. To check off the lab, your test cases should not give the expected result.

You are contributing to an open-source web browser, by making a class Bookmark. A Bookmark maintains information about a URL which a user might (re)visit frequently. In our case, Bookmarks even keep track of how many times the user has visited the bookmarked page.

Write class BookmarkTester, whose main method creates a Bookmark object and calls the following methods (behaviors).

Behaviors (methods) we want (to test), for Bookmarks:

• Construct a new Bookmark, giving the constructor a URL (e.g. "http://www.radford.edu/itec120/2009spring/tutor-PI-hours.html"). (Once constructed, a Bookmark will always refers to that same URL.)
• getURL: Ask what URL the Bookmark refers to.
  (What information, if any, must you provide when asking this question? What answer, if any, will you get back?)
• visit: Update the Bookmark's number-of-visits by one.
  (What information, if any, must you provide when asking this question? What answer, if any, will you get back?)
• getNumVisits: Ask how many visits have been recorded for the Bookmark (that is, how many times the previous method has been called).
  (What information, if any, must you provide when asking this question? What answer, if any, will you get back?)
• Optional: Set the rating for the Bookmarked page, on a scale of one star to five stars. (A brand-new page should have a rating of three stars.)
• Optional: Ask the the Bookmark's rating is.

After writing your test-class, write the method stubs for class Bookmark. Your program should compile, and your test cases print the desired and expected answers. Of course, the answers won't be the expected, correct answers since we have only written method stubs.

You may refer to the BankAccountTester and BankAccount classes from lecture. Your solution to this lab should be similar to the above two.
