Create a class named College Course that includes data fields that hold the department (for example, ENG), the course number (for example, 101), the credits (for example, 3), and the fee for the course (for example, $360). All of the fields are required as arguments to the constructor, except for the fee, which is calculated at $120 per credit hour.
Include a display () method that displays the course data. Create a subclass named Lab Course that adds $50 to the course fee. Override the parent class display () method to indicate that the course is a lab course and to display all the data. Write an application named UseCourse that prompts the user for course information.
If the user enters a class in any of the following departments, create a LabCourse: BIO, CHM, CIS, or PHY. If the user enters any other department, create a CollegeCourse that does not include the lab fee. Then display the course data. Save the files as CollegeCourse.java, LabCourse.java, and UseCourse.java.
Please submit the source code for your program along with a word document that includes screen shots of the compiled results and executed output. The page margins on the top, bottom, left side, and right side should be 1 inch each.
