Create a class named CollegeCourse 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 LabCourse 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. 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.
