Task Set. Priorities range from 1 to 4, where a lower numeric value indicates a higher relative
priority. For round-robin scheduling, the length of a time quantum is 10 milliseconds.
The following four scheduling algorithms should be implemented in four different threads using
Java programming language. The main thread in your program will finally print on console the
generated schedule using a modified Gantt chart, average waiting time, and average turnaround
time for each algorithm.
1. First-come, first-served (FCFS) assuming all the tasks arrive at the same time.
2. Shortest-job-first (SJF) assuming all the tasks arrive at the same time and also breaking
ties randomly.
3.
Preemptive priority scheduling (PS) using the priorities given in the task set and using a
random arrival time (in ms) in the interval [0, 100] for each task. You must generate
random arrival times using a java random number generator function. You must also print
the arrival times generated by your program before you print this schedule.
4. Round-robin (RR) scheduling, where each task is run for a time quantum (or for the
remainder of its CPU burst).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F33eba9e5-eb7d-44a1-93e3-ed0ee897e17f%2Fe3ea3a62-d01d-457e-92bf-e6aaf516107d%2Fu8gwidb_processed.png&w=3840&q=75)
