- Can i get solution for b a. Create a CourseException class that extends Exception and whose constructor receives a String that holds a college course’s department (for example, CIS), a course number (for example, 101), and a number of credits (for example, 3). Save the file as CourseException.java. Create a Course class with the same fields and whose constructor requires values for each field. Upon construction, throw a CourseException if the department does not consist of three letters, if the course number does not consist of three digits between 100 and 499 inclusive, or if the credits are less than 0.5 or more than 6. Save the class as Course.java. Write an application that establishes an array of at least six Course objects with valid and invalid values.
