What TWO JAVA STRUCTURAL DESIGN PATTERNS can be implemented using the class diagram provided? In the Programming language JAVA, construct TWO SEPARATE CODES using the TWO STRUCTURAL PATTERNS.
Construct TWO STRUCTURAL PATTERN CODE FOR THE FOLLOWING SCENARIO:
The Computer Science department offers the following programs:
- Degree Programs -- Undergraduate: 4-year Bachelor of Science (B.S.) in CS (Computer Science) and CIS (Computer & Information Systems); Graduate: 2-year Master of Science (M.S.) in CS, CIS, and DA. Each of these programs requires a fixed number of core courses (determined by the department) and a fixed number of elective courses (the student picks the electives from the choices particular to the program). Let us assume that a year is made up of two semesters. For the B.S. and the M.S. programs, students take only the electives in their last year of study. For both the programs, students does an additional thesis in their last semester.
- Certificate Programs in various concentrations (Security, Web Technology, Analytics, etc.) -- each program requires 4 courses. These programs have no time limit, and a student gets the certificate whenever the course requirements are met.
The department has a Chairperson, full-time faculty, and part-time faculty. The Chairperson and the part-time faculty teach only one course per semester, whereas the full-time faculty teach three courses each semester. Among the full-time faculty, there will be a single Graduate advisor and a single Undergraduate Advisor. The advisors serve in that capacity for a year. Students can send a query to their advisor as well as the Chairperson and any faculty. Full-time faculty also serve as the thesis advisor for the students.
The courses offered by the department are grouped under various concentration areas (e.g., Systems, Programming Languages, Databases, Software Engineering, etc.). A concentration would have a collection of courses, or if the concentration is a wide one, it will be organized into a hierarchical structure with sub-concentrations. For example, the Programming Languages concentration could have sub-concentrations like Procedural Languages, Object Oriented Languages, Functional Languages, and so on. Let us assume that a given course is taught by the same faculty person each and every time. A full-time faculty member is responsible for coordinating each concentration (or sub-concentration). A full-time faculty member can be the coordinator for more than one concentration (or sub-concentration). The overall responsibility for the top-level concentrations lies with the chairman.
Each course has a description, syllabus, and a method named format, which returns an HTML format output of the course. Each concentration also has a description and the method format, which recursively calls the format of its components and returns an HTML format output for the concentration.
For a given student, we should be able to tell what program the student is enrolled in, what courses are taken by the student each semester, what their thesis is, and the thesis advisor (if applicable). Also, provide the method, GPA, which computes the GPA of the student (assume each course is 4 credits and the following points for the grades: A (4), B (3), C (2), D (1), F(0)
The Department keeps track of the courses offered each semester. The department also wants to know the students enrolled in a given course for a particular semester.
A faculty member should easily know what courses they are teaching a given semester and the students they are advising for that semester.
Students enroll for courses for a given semester with the department. Each course has an enrollment limit, and when the limit is reached, the Chairperson will be notified automatically. Students will be wait-listed when the course limit is reached. When a student drops from such a course, the first person on the waitlist for that course will be notified and enrolled automatically
- Demonstrate students enrolling/dropping in classes and the notification to the chairperson when an enrollment limit is reached. Also, demonstrate the case when a student is wait-listed, and an opening occurs for that course. You can hard code the data about the semesters, courses, and enrollment limits without having a need for an explicit database.
