Chapter 9, Problem 19E

Create tests for SalesItem that test whether the find-MostHelpfulComment method works as expected. Note that this method returns a Comment object. During your testing, you can use the Get button in the method result dialog to get the result object onto the object bench, which then allows you to make further method calls and add assertions for this object. This allows you to identify the comment object returned (e.g., by checking its author). You can also assert that the result is null or not null, depending on what you expect.

PLEASE ENSURE TO USE THE FRAMEWORK PROVIDED IN THE IMAGES, AND THAT IT WORKS WITH THE TESTER CLASS. PLEASE EDIT BOTH THE TEST CLASS, DO NOT EDIT THE MAIN METHOD. Write a BankAccountTester class whose main method constructs a bank account, deposits $1,000, withdraws $500, withdraws another $400, and then prints the remaining balance. Also print the expected result.
Write a main method, in which you should have an Arralylist of students, in which you should include every student. You should have a PhD student named Joe Smith. In addition, you should create an Undergraduate student object for each of your team members (setting their names). If you’re only one person doing the assignment, then you should just create one undergraduate object. For each undergraduate student, you should add add two courses (COIS 2240 and COIS 1020). Loop over the arraylist of students, print their names, if the student is an undergraduate student, print their courses.
Create a code the follow way:  Each student object should also contain thenumber of earned credits. Provide a constructor that sets this value based on parameter value. Overload theconstructor such that the number of earned credits is initially zero. Provide setter and getter for this newfield. Modify the toString method such that the new information is included in the description of thestudent. Modify the driver class main method to exercise the new Student methods.
