9.7 LAB: Find student with highest GPA (EO) Complete the Course class by implementing the findHighestStudent() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: 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 private fields: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPA Brenda Stern with 2.0 GPA Lynda Robison with 3.2 GPA Sonya King with 3.9 GPA then the findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9) 289222.1747582.qx3zqy7 LAB ACTIVITY 9.7.1: LAB: Find student with highest GPA (EO) 0 / 10
