1. Create a class named Student with private fields: first (String), last (String), and gpa (double).

2. Implement a constructor in the Student class to initialize first, last, and gpa.
3. Implement getGPA() method in the Student class to retrieve the GPA of the student.
4. Override toString() method in the Student class to return a formatted string representation of the student.

5. Create a class named Course with an ArrayList of Student objects named roster.
6. Implement a method named findStudentHighestGpa() in the Course class.
7. Initialize a Student object variable (highestGpaStudent) to null to keep track of the student with the highest GPA.
8. Iterate through the roster list:
   a. For each student, compare their GPA with the GPA of highestGpaStudent.
   b. If the student's GPA is higher, update highestGpaStudent with the current student.
9. After iterating through the roster, highestGpaStudent will contain the student with the highest GPA.
10. Return highestGpaStudent from the findStudentHighestGpa() method.
