Shortest Job First scheduling algorithm in Java

By Vipul Rajesh Chandankar

  • SJF.java
  • output.jpg

    • In this project shows the programmatic implementation of Shortest Job First Scheduling Algorithm in Java. Here we calculated the Average waiting time and Average Turn Around Time.

    Shortest Job First (preemptive) : In this scheduling algorithm, the process with the smallest brust time is selected for execution. If a process with even a shorter burst time arrives, the current process is removed or preempted from execution, and the shorter job is allocated CPU cycle.

    Pros :

    1) SJF is frequently used in long term scheduling process.

    2) It reduces the average Waiting Time for a specific set of process

    3) It is appopriate for the job running in batch, where run time is known is advance.

    Cons :

    1) It require the knowledge about how long will process will run

    2) It lead to starvation
