Question

• Create Course object class (Course.java)
  • Course object should be the following attributes:
    • Course id:12345
    • Instructor id: 9876
    • Room id: 101

I have everything written out but it won't compile, any help?

public class Course
{
   private int course id;
   private int instructor id;
   private int room id;

   Course()
   {
       setCourseID (13233);
       setInsID    (001);
       setRoomID    (101);
   }

   Course(int courseID, int instructorID, int roomID)
   {
       setCourseID    (courseID);
       setInsID        (instructorID);
       setRoomID        (roomID);
   }

   public int getCourseID()
   {
       return courseID;
}

public int getInsID()
   {
       return instructorID;
}

public int getRoomID()
   {
       return roomID;
}

{
       System.out.println("Course ID : " + getCourseID());
       System.out.println("Instructor ID : " + getInsID());
       System.out.println("Room ID : " + getRoomID());
   }
}

Answer 1

public class Course {
    private int courseID;
    private int instructorID;
    private int roomID;

    public Course() {
        setCourseID(13233);
        setInsID(001);
        setRoomID(101);
    }

    public Course(int courseID, int instructorID, int roomID) {
        setCourseID(courseID);
        setInsID(instructorID);
        setRoomID(roomID);
    }

    public int getCourseID() {
        return courseID;
    }

    public int getInsID() {
        return instructorID;
    }

    public int getRoomID() {
        return roomID;
    }

    public void setCourseID(int courseID) {
        this.courseID = courseID;
    }

    public void setInsID(int instructorID) {
        this.instructorID = instructorID;
    }

    public void setRoomID(int roomID) {
        this.roomID = roomID;
    }

    public void print() {
        System.out.println("Course ID : " + getCourseID());
        System.out.println("Instructor ID : " + getInsID());
        System.out.println("Room ID : " + getRoomID());
    }

    public static void main(String[] args) {
        Course course = new Course();
        course.setCourseID(7);
        course.setInsID(77);
        course.setRoomID(17);

        course.print();
    }
}
