Question

I need help to do the program of the next homework. A teacher has 14 students in a course and he wants save information of them and about the course. From the students, he wants save the students: names, position in a classroom, studied carrier, what programs they know, the test grades, the projects grades, the participation in class grades. And also each student will belong to a one group (there are three different groups A,B,C). The course has 5 blocks: Java SE, Java EE, Web, BBDD, Projects and he would like to save information of the subjects studied in each block. Part I: UML · Make the UML diagram that includes the main elements

Explanation / Answer

Hi ..

import school.*;
import school.courses.*;

public class Main {
public static void main(String[] args) {
Teacher sriram = new Teacher("sriram");
Teacher bharat = new Teacher("bharat");
Teacher lil = new Teacher("Lil");
Teacher jana = new Teacher("jana");

Course[] courses = {
new NetworkCourse(15, sriram),
new SwingCourse(30, bharat),
new APIDesignCourse(50, lil),
new PerformanceCourse(5, jana)
};
School school = new School(courses);

Student ludwig = new Student("Ludwig");
Student cam = new Student("Cam");
Student daniel = new Student("Daniel");   
ludwig.setPreferredCourses(NetworkCourse.class, SwingCourse.class); //give students preferred classes if they have them
cam.setPreferredCourses(APIDesignCourse.class, PerformanceCourse.class, NetworkCourse.class);

school.register(ludwig, cam, daniel);

/*
* Below is where we test by printing things out
*/
test(school);
}

static void test(School school) {
/*
* Prints all the students in the school, all the courses in the school, and which course each student has
*/
System.out.println("Students and their courses:");
for(Student student : school.getStudents()) {
if(student != null) {
String message = student.getName() + " is taking"; //message will reset for each new student, since we do = and not += here

for(Course course : student.getCourses())
message += " - " + course.getName();

System.out.println(message);
}
}

System.out.println(" Courses and their students:");
for(Course course : school.getCourses()) {
String message = course.getName() + " is taken by";

for(Student student : course.getStudents()) {
if(student != null)
message += " - " + student.getName();
}
System.out.println(message);
}
}
}------------------------------

package school;

import java.util.*;

public abstract class Course {
private Teacher teacher;
private Student[] students;
private UUID id;

protected Course(int maxStudents, Teacher teacher) { //might allow multiple teachers later
students = new Student[maxStudents];
this.teacher = teacher;

id = UUID.randomUUID();
}

void addStudent(Student student) {
for(int i = 0; i < students.length; i++) {
if(student == students[i])
continue;

if(students[i] == null) {
students[i] = student;
return;
}
}
}   

public Teacher getTeacher() {
return teacher;
}

public Student[] getStudents() {
return Arrays.copyOf(students, students.length);
}

public boolean isFull() {
boolean full = true;

for(Student student : students)
full = student != null;

return full;
}

public abstract String getName();
}

thanks
