- Write a program that support all five scheduling algorithms using Java programming language. Your work should be implemented in object oriented approach. The program must have the following classes; - Process - FCFS - SJF - SRTF - RR - Priority - Main Tips: - A group of two students should complete the assignment. - For each 24-hour late submission, 1 mark penalty counted. - Copying/distribution is strictly prohibited. In such case, both sides will loss marks. - Write necessary constructors and methods for all classes. - The program should have an output as shown in below figure. The result of all scheduling algorithms with their Gantt Chart are printed consecutively.

TAsk 1 Create a CPN model based on the AOM Goal and Behavioural Interface Models using the mapping heuristics discuConsider the following scenario:You are required to design and implement a system that will be used to take online exams. There are two main groups of users, teachers, and students. Teachers can schedule exams and add students by their email addresses. The teacher should also be able to create student groups. Student groups can be comprised of other student groups. Teachers, if they so wish, can add students to an exam by adding individual students, and/or groups. Half an hour before the scheduled time of the exam, the students should get a notification via email.Exam assessment is done on a per-question level. For each question, the teacher can set one out of many assessment methods (e.g. content-matching, MCQ, mathematical correctness, manual marking, etc.), with each method having its own parameters as specified by the teacher. Certain questions can have nested questions. When an assessment method is set for these, the teacher should be given the choice to apply the same assessment…
