The code above outputs the following: |=| GANTT CHART |=| Public Pair(int time, String processState) * represents one pair (time and processState) and keep these pairs * Saves process State in an ArrayList to output after simulation ends. RoundRobin.ps.printf('%-1s%.2f%1s%n', 'Throughput: ', RoundRobin.getThroughput(cpu), RoundRobin.ps.printf('%-1s%.0f%1s%n', 'Utilization Rate: ', RoundRobin.getUtilizationRate(cpu), '%') RoundRobin.ps.println('Average Turn Around Time: ' + RoundRobin.getAverateTurnAroundTime()) RoundRobin.ps.println('Average Waiting Time: ' + RoundRobin.getAverageWaitingTime()) RoundRobin.increaseWaitingTimeToWaitingProcesses(waitingQueue) įirst += '| ' + current.getProcessState() + ' |' verify if all processes have finished processing. if there is a process assign it to the waiting queue. sending it back to the end of the ready queue. context switch by removing the current process and If (process.getProcessedBurstTime() % RoundRobin.timeQuantum = 0)

proccess, if so continue to the next process in queue. check if the CPU has Finished processing the previous Pairs.add(new Pair(cpu.getTime(), cpu.getProcess().getName())) Pairs.add(new Pair(cpu.getTime(), 'IDLE')) if the waiting queue is empty then that means that the if the CPU is not busy then get one of the process in the LinkedList arrivedProcesses = RoundRobin.getArrivedProcessed(cpu.getTime()) check if there are processes that has arrived and add them to the RoundRobin.ps.println('Process Name | Arrival Time | Burst Time |') RoundRobin.ps.printf('%27s%n', 'PROCESSES') RoundRobin.ps.println('TIME QUANTUM: ' + RoundRobin.timeQuantum) RoundRobin.ps.println('ROUND ROBIN SIMULATION RESULT') Before starting the simulation, print first the generated processes * Display Process table and Processes Execution Sequence This is a round Robin CPU Scheduling program. I have been trying to create a gantt chart with the output of my program but i can't seem to figure out how to do it.
