Java Help

1. You need to read the CPU Burst Time of processes for your scheduling algorithms from the keyboard as follows:

Please enter the CPU Burst Time for Process #1 (-1 to exit): 10

Please enter the CPU Burst Time for Process #2 (-1 to exit): 29

Please enter the CPU Burst Time for Process #3 (-1 to exit): 3

Please enter the CPU Burst Time for Process #4 (-1 to exit): 7

Please enter the CPU Burst Time for Process #5 (-1 to exit): 12

Please enter the CPU Burst Time for Process #6 (-1 to exit): -1

2. Your program (scheduler.java) should support these options: FCFS, SJF, Exit. Which scheduling algorithm would you like to use? (FCFS, SJF, Exit): FCFS

Implement FCFS and report sequence of execution (begin time and end time for each process CPU burst), average waiting time and average turnaround time.

========================================== FCFS SCHEDULING ALGORITHM: ==========================================

PID Start Burst End Burst

1 0 10

2 10 39

3 39 42

4 42 49

5 49 81 Average waiting time: 28.00

Average turnaround time: 40.20 ==========================================

Which scheduling algorithm would you like to use? (FCFS, SJF, Exit): Exit

4. Implement SJF (non-preemptive) and report sequence of execution (begin time and end time for each process CPU burst), average waiting time and average turnaround time.
