Can you create a java program that will make a CPU SCHEDULER w/ First Come First Serve,Round Robin,Priority Scheduling(Preemptive & Non-Preemptive)& Shortest Job First(Preemptive & Non-Preemptive)
that will compute for Waiting time,Average waiting time,turnaround time and throughput
If you have done threads with Java, you could programme each of the scheduling algorithms, and simulate the operation and obtain statistics using random data.
If you have not done threads, you can still simulate the operation of the scheduling, by assuming a discrete (constant) time for each operation.
We will be glad to help you with your work, but we do not write the programme for you.
Yes, I can help you create a Java program that implements a CPU Scheduler with First Come First Serve, Round Robin, Priority Scheduling (Preemptive & Non-Preemptive), and Shortest Job First (Preemptive & Non-Preemptive) algorithms. Here's a step-by-step guide on how to build this program:
Step 1: Define a Process class
- Create a Process class with attributes like process ID, arrival time, burst time, priority, etc.
- Include getter and setter methods for these attributes.
Step 2: Implement the CPU Scheduler algorithms
- For each scheduling algorithm, you'll need to implement methods to calculate waiting time, average waiting time, turnaround time, and throughput.
- Each algorithm will have its own logic for process scheduling, such as sorting processes based on arrival time or priority, executing them based on a specific algorithm, etc.
Step 3: Main program logic
- Create a main class that will contain the main method and user interface.
- Prompt the user to input the number of processes and other required information for each process (arrival time, burst time, priority).
- Initialize the process objects using the input and add them to a process list.
Step 4: Method implementation
- Implement methods to calculate waiting time, average waiting time, turnaround time, and throughput for each scheduling algorithm.
- Use loops and conditional statements to execute the algorithms based on the predefined logic.
- Perform computations based on the formulas defined for each metric.
Step 5: Display the results
- After executing each algorithm, display the results, including waiting time, average waiting time, turnaround time, and throughput.
Note: The detailed implementation of each algorithm is beyond the scope of this explanation. However, you can find code examples and resources online to guide you through the implementation of each scheduling algorithm.
Remember to handle edge cases, validate user inputs, and ensure that the program provides accurate results.
By following these steps, you should be able to create a Java program that implements a CPU Scheduler with the required algorithms and computes the metrics you mentioned. Good luck!
