I need help to create a working java program, and these are the instructions:

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. 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.
