JAVA - In this assignment you will develop and implement a discrete simulator (single-threaded) that implements a five-level multilevel feedback queue. A feedback queue is a technique used in operating systems to schedule processes for execution with the goal of optimizing turnaround time and minimizing response time. The structure of the scheduler is given in Figure 1. Each of the five levels of queues and the associated time quantum are as follows: Ready queue, 0 units, FCFS input Level one (entry level), 1 units, preemptive FCFS Level two, 2 units, preemptive FCFS Level three, 4 units, preemptive FCFS Level four, 6 units, preemptive FCFS Level five (bottom level), 8 units, round-robin FCFS = First Come First Served The program must accept input from a text file which contains the process number (one byte, arbitrary), arrival time (integer, in units), and execution duration (integer, in units). For example, 7~15~6 denotes process number 7, which arrives at time 15 and will execute for 6 time units. It is assumed that each file will contain jobs in arrival time order; however, if the input file is not in the correct sequence, then your program must ensure that the jobs are placed in the ready queue in the proper sequence. The default name of the input file is, jobs.txt, but the name and path to the file must be able to be overridden from the command line. The default output file is named, traceout.txt, but the name and path to the file must also be able to be specified from the command line. A sample command line is provided below. The first command line parameter is assumed to be the input file name and path. The default files should be placed in the current working directory.
