Question

Write a class called Course_xxx that represents a course taken at a school. Represent each student using the Student class from the Chapter 7 source files, Student.java. Use an ArrayList in the Course to store the students taking that course. The constructor of the Course class should accept only the name of the course. Provide a method called addStudent that accepts one Student parameter. Provide a method called roll that prints all students in the course. Create a driver class School_xxx with a main method that creates a course, adds several students, and prints a roll.

Submit School_xxx.java and Course_xxx.java where xxx are your initials.

Student.java

public class Student

homeAddress = home;
schoolAddress = school;
}

//-----------------------------------------------------------------

public String toString()
{
String result;

result = firstName + " " + lastName + "\n";
result += "Home Address:\n" + homeAddress + "\n";
result += "School Address:\n" + schoolAddress;

return result;
}
}

Please include commentary/documentation for me to better understand the code. Thank you!

COURSE.JAVA

package abc;

import java.util.ArrayList;

import java.util.List;

public class Course {

private String courseName;

private List<Student> students= new ArrayList();

//constructor of the Course class that accepts only course name

public Course(String courseName) {

super();

this.courseName = courseName;

}

//addStudent method accepts one Student parameter

public void addStudent(Student student) {

students.add(student);

}

//roll method that prints all students in the course

public void roll(Course course) {

System.out.println("Course name: "+course.courseName);

System.out.println("Students registered for the course "+course.courseName+" :");

System.out.println("======================================");

for (Student student : course.students) { //looping through all the students enrolled for that course

System.out.println(student);// calls to string method of student class

System.out.println("======================================");

}

}

Student s1 = new Student("Andrew", "K", homeAddress1, schoolAddress1);

course1.addStudent(s1); //andrew is added to java course

//calling roll method of course to print the students enrolled for the course

course1.roll(course1);
