Complete the Course class by implementing the printRoster() method, which outputs a list of all students enrolled in a course and also the total number of students in the course. Given classes: • Class LabProgram contains the main method for testing the program. • Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) • Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex: If the program has 4 students enrolled in the course, the output looks like: Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4
