Q8. Write a declaration of a private field named department that can hold an ArrayList. The elements of the ArrayList are of type Student. Write an assignment to the department variable to create an appropriate ArrayList object.

Create a class called Student that models a student at Carleton University. A student's state consists of a name (String), id number (int) and a list of grades (array of double). Your class must have a constructor that has three input parameters (name, id and grade list) and sets the initial state for the object. Include a toString() method that returns a useful string representation of a student object. The string representation should contain the student's name, ID number, and the number of grades they have recorded (so NOT include all the grades). Include a gradesInRange(double lower, double upper) method that returns the number of grades that this student has that are in the range [lower,upper]. That is, the it returns the number of grades that are greater than or equal to lower and less than or equal to upper. Example Usage: double[] grades {81.2, 93.2, 76,2, 84.6, 63.11, 79.8}; Student s new Student("cat", 100123987, grades); s.gradesInRange (80,100); int num_grades_A // assert…

Hello all! Need some help with this assignment. Need to create an array of 8 employees ( see image for details ) Thank you!

Complete the Course class by implementing the courseSize() method, which returns 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. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram {    public static void main (String [] args) {       Course course = new Course();            // Example students for testing      course.addStudent(new Student("Henry", "Bendel", 3.6));         course.addStudent(new Student("Johnny", "Min", 2.9));              System.out.println("Course size: " + course.courseSize());    } }   public class Student {     private String first;  // first name    private String last;   // last name    private…
