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 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. (Hint: toString() returns a String representation of the Student object.)
Ex: If the following students and their GPA values are added to a course:
Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA
then the program output is:
Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4

4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print
them to the console. What would the code look like for this?
5. Write a method signature for a method called foo that takes an array as an argument. The
return type is void.
6. What is the difference between remove and clear in ArrayLists.

It should maintain the public size variable that keeps track of the number of students registered. • getRegisteredIDs() – returns an array of int[], namely registered student id’s. The length of the array is the size (number of students) in the course. • getRegisteredStudents() – returns an array of type Student[], namely the registered Students. The length of the array is the current size (number of students) of the course. • getWaitlistedIDs() – returns an array of type int[], namely the ids of students in the waitlist. • getWaitlistedStudents() – returns an array of Students in the waitlist. public class Course { public String code; public int capacity; public SLinkedList<Student>[] studentTable; public int size; public SLinkedList<Student> waitlist; public Course(String code) {…arrow_forward
- Which best describes this axiom: ( aList ( ) ) . replace ( i, item ) ) . getEntry ( i ) = item When an item is replaced, it always goes in the position specified in the method call When an item is replaced, space is made by moving all of the items starting at the position specified down toward the bottom of the list by one to make room When an item is replaced, it always goes in the first available unused position None of thesearrow_forwardWrite a method called changeQueue to be considered inside the ArrayQueue class and has one parameter item of type E. Your method will change the queue in such a way that if the the first element of the queue and the last element of the queue are equal, the first and last elements in the queue will be replaced with item, otherwise, do not do any change. Similarly, the same process is done for the second element in the queue and the element before the last in the queue and so on. Assume you have a non-empty queue with even number of elements. You are not allowed to call any method from the the ArrayQueue. class. Do not use iterators. Method head: public void changeQueue(E item) Examplet: Before run: front rear "this" queue: 10 29 2 25 10 Item1: 100 After run: front rear "this" queue: 100 29 100 100 5 100 Use the editor to format your answerarrow_forwardMake a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class; these two classes will need to be in two separate files.

The method is to be in a class called VaccinationQueue and has two parameters q1 and q2 type ArrayQueue. The q1 and q2 data are of type Integer. Assume that initially q1 is not empty and q2 is empty. The method will insert from q1 those elements towards the beginning of the queue (front) q2 whose data is greater than or equal to 45 and will insert those elements whose data is less than 45 and greater than or equal to 18 towards the end (rear) of q2. Any data item less than 18 of q1 will not be inserted in q2. It returns the number of elements added to q2. Class ArrayQueue and all its methods including iterator are available for use. You can also create temporary queues. You are not allowed to use arrays or any other data structure.
