after learning about thread in java, I realized that we cannot update UI in swing in another thread because components are not thread safe. So, you must use this code if you want to execute this program: replace your simulate method's code by //while(!Simulation.Finished){ new Thread(new Runnable() { public void run() { while(!Simulation.Finished){ // Runs inside of the Swing UI thread SwingUtilities.invokeLater(new Runnable() { public void run() { nextStepBttnActionPerformed(null); System.out.println("nguyen thanh tai"); } }); try { java.lang.Thread.sleep(1000); } catch(Exception e) { } }
Hi, I had downloaded the complete project from the description but when I try to run the program from Netbeans , the Gantt Chart & Ready Queue not running after 'Simulate' button pressed. However, if you press 'finish' button, the Gantt Chart only display. Any bugs on the program ?
i have the same problem, sir please could you help with this?? the Gantt Chart & Ready Queue not running after 'Simulate' button pressed. However, if you press 'finish' button, the Gantt Chart only display. Please help out sir.
Hi, the Simulate Button is not working, I tried to manipulate the simulation method but I got no luck. Can you please provide me what solutions for this? just like the video you have showed thanks a lot.
Hey your Code is well but my problem is there in main function "face" extends cpu but there is no show function there is only show method have there.? and the query face and AppData have main function but there is only exception i want to know where is main function actually calls.. any specific file..??
How can I solve this error? Exception in thread "main" java.lang.NullPointerException at javax.swing.ImageIcon.(Unknown Source) at cpu.Face.initComponents(Face.java:673) at cpu.Face.(Face.java:23) at cpu.CPU.main(CPU.java:11)
@@ahmed.elmowafy cpu.java like face.java, simulate button doesn't work like in the video. and I have downloaded the full java project in the description box. please the solution
Here in this program, we use the same data with all of the algorithms to be able to see the difference between them in action. so if RR doesn't need priority, it won't use it.
@@ahmed.elmowafy can you give me the complete java project jar file? I tried to enter the webpage. but the webpage has been blocked . Please send me the the java jar file. I need it for my OS project
hi..i just want to ask, i already downloaded the source code of this project and already run it at netbean. but the problem is when i try to execute it it will not run automatically. what do you think is the problem?? thank you in advance for answering this question.
Hi, thanks for sharing this :). I'm having problems adding my own data in the "job pool". I do the following: file->add my data->write some values between ur contraints->load. But it just assign random values. Is it possible to fix this? Thanks :)
Thanks for replying :). It doesn't work with any value at all; for example, after starting the program, i do the following: file, add my data, arrive burst priority 0 0 0 5 9 0 11 3 0 12 10 0 and then i press load, but the job pool remains empty. I'm using Linux Mint KDE, running the jar file via "Konsole", with this java version: java version "1.7.0_79" OpenJDK Runtime Environment (IcedTea 2.5.6) (7u79-2.5.6-0ubuntu1.14.04.1) Also, "Simulate" button doesn't do anything. Ps. I tried "sudo java -jar CPU.jar" and java on windows 8.1 but nothing changes. Going to recompile the whole project
salam, hello sir, i have a question can this program able to simulate more than 100 of jobs? where can i change the num job of task in the coding? thanks again sir.
As specified here : github.com/Mowafy/CPU-Schedualing-Algorithms-Simulator/blob/master/src/cpu/MainQueue.java number of jobs is an integer number so it can take up to 2 billion jobs (or what your RAM can hold) and the code will work fine with that (except it will take longer time). But, there is a constrain only in the GUI representation in this program that will arise if you raised the number of jobs more than 8, you will need to scroll in the job pool table, the gantt chart and the ready queue to view the hidden jobs, and you will need to assign a different color for every single job in the representation. If you have any question, please feel free to ask.
What are you trying to accomplish here? Obviously you can't change quantum value in the GUI unless you are using the RR algorithm, and the RR algorithm java class is taking quantum value as an argument, so no it's not fixed.
when i choose the RR algorithm from the gui and choose for example 7 as Quantum the result in the gantt chart shows as if the Quantum is equal to 2. i know the RR.java takes quantum value as an argument from Simulation but the Quantum value at Simulation was never changed from "2" even though i selected 7. idk if i am the only one facing this problem but i have solved it. if you don't have the same problem, don't bother.
Oh, i've got it now.. thank u but there's an error.. it could not find face, says CPU.java when i run it... It's error is in the constructor of Face face= new Face();
+Ahmed Elmowafy is this project open in netbeans or eclipse IDE? how to open this project on IDE When i run this project it is not respond that is shows in your video please help me out

How to test or present this application using src code link that you mentioned.
i have zero idea on java but i just wanna see how to simulate this so i downloaded the full java project but i dont know how to run it :-( plz help
You need to install java, then run the jar file
thanks for the response, do i have to download that separately from the full project?
www.java.com/en/download/
Ahmed Elmowafy how do i open the project in java? There are errors when i open the .java files from the project
You can download the full java project in the description

Why my gantt chart is stock and when i hit finish the simulation done

@@safiratanty537 It seems that you need to debug it. For its worth, the simulate button acts like pushing the "next step" button repeatedly.
Can you please tell me why isn't the simulation animation coming.. After I select finish it shows the entire gnatt chart together!

Good day!
I just ask, why in RR need to input the priority? Coz in our lesson it is just the burst time, arrival time and quantum slice.
Here in this program, we use the same data with all of the algorithms to be able to see the difference between them in action. so if RR doesn't need priority, it won't use it.

sir simulate key is not working please help
turns out the Quantum was fixed at 2 in the code in the RR.java file. Thanks though
I've just checked the RR.java file, and there is no "2" written there in the file!
i'm sorry. it was the Simulation.java
What are you trying to accomplish here?
Obviously you can't change quantum value in the GUI unless you are using the RR algorithm, and the RR algorithm java class is taking quantum value as an argument, so no it's not fixed.

You must restart the simulation for the quantum change to take effect, as its value is sent to the algorithm class at the creation of the object.

yes... i've tried downloading and extracting it again but every time i open its folder, i really couldn't find the cpu.face.. i only find cpu.java
CPU is the namespace
so the file is "face.java"
you could open the project by NetBeans and it'll save you all the hard work.
