* Help: Java Code For Cpu Scheduling Algorithm

[coldvoice05]

PLEASE GUYS I NEED A JAVA SOURCE CODE THAT SHOWING THE 5 OUT OF 6 CPU SCHEDULING ALGORITHM
*FCFS- FIRST COME FIRST SERVE
*SJN- SHORTEST JOB NEXT
*PS- PRIORITY SCHEDULING
*SRT- SHORTEST REMAINING TIME
*RR- ROUND ROBIN

as of now I come up with this code but its not complete.... please guys help me finish this code ASAP

Java and CPU scheduling don't go together. I'm not sure what you are doing, but Java doesn't sound like the right approach...

How about if someone will need or a user will input also a given arrival time??

I know that it would be complex but it seems that it is needed for thorough simulation,..
