Question

write java program and for the following

(you can add more classes as you see necessary) as follows:
a class called Coursewith courseCode, courseName,and creditHours;
a superclass called FacultyMemberwith FacultyID, firstName, lastName, academicRank,
and academicSpecialization;
a course Convener subclass inherits from the FacultyMember class with specific member variables representing the coursesand members (Lecturers andTAs) whom
he/she is responsible of; Lecturers andTAsare also subclasses that inherit from FacultyMemberclass with some specific member variables (i.e., maximumNumberOfCourses, quotaOfCreditHoursthey can take, and assignedCourses).

Create a project called TaibahCSand implement your class diagram that must include: Course, FacultyMember, Convener, Lecturers, andTAs.
Declare some overloaded constructors with parameters for all classes, and some appropriate methods as you suggest.

Answer 1

CODE FOR ABOVE PROBLEM

Course.java

package teaching;

public class Course {
  
   String courseCode;
   String courseName;
   int creditHours;
   //constructor for course
   public Course(String courseCode, String courseName, int creditHours) {
       this.courseCode = courseCode;
       this.courseName = courseName;
       this.creditHours = creditHours;
   }
  
   //toString method which return the course object in string form
   public String toString() {
       return "Course [" + courseCode +" " + courseName + creditHours + "]";
   }
}

FacultyMember.java Code

package teaching;

public class FacultyMember {
  
   String facultyId;
   String firstName;
   String lastName;
   int acadamicRank;
   String acadamicSpecialization;
   //constructor for facultMember class
   public FacultyMember(String facultyId, String firstName, String lastName, int acadamicRank,
           String acadamicSpecialization) {
       this.facultyId = facultyId;
       this.firstName = firstName;
       this.lastName = lastName;
       this.acadamicRank = acadamicRank;
       this.acadamicSpecialization = acadamicSpecialization;
   }
   @Override
   public String toString() {
       return "FacultyMember ["+ facultyId +" " + firstName +" "+ lastName
               +" "+ acadamicRank +" "+ acadamicSpecialization + "]";
   }

}

}

TA.java Code

package teaching;

   }
   public String toString()
   {
       return "TA[ "+maxNoOfCourses+" "+quotaOfCreditHours+" Assigned Courses:\n"+assignedCourse.toString();
   }
}

Conviner.java Code

package teaching;

public class Convener
{
   Course course;
   FacultyMember member;//member can be either TA or Lecturers
   public Convener(Course course, FacultyMember member) {
       this.course = course;

   }

  

   @Override
   public String toString() {
       return "Convener [" + course +" " + member+"]" ;
   }
}

TaibahCS.java Code

package teaching;

import java.util.ArrayList;

public class TaibahCS {

   public static void main(String[] args) {
      
       ArrayList<Course>list1=new ArrayList<Course>();
       list1.add(new Course("Java101","Object Oriented",25));
       list1.add(new Course("C102","C Programming",17));
       list1.add(new Course("DLD53","Digital Logic and Design",15));
       list1.add(new Course("OS103","Operating System",10));
       //creating object of TA
       FacultyMember ta=new TA("TAId1","Sudeepthi","Maruvada",34,"CSE",5,5,list1);
      
       System.out.println(ta);
      
       ArrayList<Course>list2=new ArrayList<Course>();
       list2.add(new Course("DBMS201","DataBase Management",15));
       list2.add(new Course("CNS203","Cryptography",18));
       list2.add(new Course("SE204","Software Engineering",20));
       //creating object of Lecturer
       Lecturers lecturer=new Lecturers("LecId1","Kowlutla","Mangali",2,"CSE",3,5,list2);
      
       System.out.println(lecturer);
      
       //passing above two objects to Convener class
      
       Convener convener=new Convener(new Course("Java101","Object Oriented",25),ta);
       System.out.println(convener);

   }

}
