Write a java program to simulate job scheduling in an operating system. It requires: Basic processes with PCB (storing process current state, pointer to the current instruction) and calculate I/O yield instructions. Creating new processes per user demand and as many as user requires Implementing one scheduler (but not FCFS) and using it to schedule processes for execution 1. 2.
