Here you will get java program for shortest job first (sjf) scheduling algorithm, both preemptive and non-preemptive. Shortest job first scheduling algorithm can also be known as shortest job next scheduling. It is very easy to implement and efficient in reducing average response time. Now we will see how it will work with the example
