JProcessDetection

What is this?

This is a simple library for detecting processes on Windows, macOS, and Linux. For example, you can check if the user have notepad.exe running(Windows) You can also add a listener to the process, so you can detect when the process is started or stopped and run some code when it happens.

Support

OS	Support
Windows	✔️
macOS	Implemented but not tested
Linux	✔️

How to use?

You will need to instantiate a ScheduledExecutorService and then the ProcessDetector class, and override the OpenClose interface.

        ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(5);

        new ProcessMonitor(scheduler, "Notepad.exe", new OpenCloseListener() {
            @Override
            public void onProcessOpen() {
                System.out.println("notepad Opened");
            }

            @Override
            public void onProcessClose() {
                System.out.println("notepad Closed");
            }
        }, 1, TimeUnit.SECONDS).startMonitoring();

        new ProcessMonitor(scheduler, "cmd.exe", new OpenCloseListener() {
            @Override
            public void onProcessOpen() {
                System.out.println("cmd Opened");
            }

            @Override
            public void onProcessClose() {
                System.out.println("cmd Closed");
            }
        }, 1, TimeUnit.SECONDS).startMonitoring();
    }

You could also use the static method to check if a process exists or not at the current time.

class Main{
    public static void main(String[]args){
        boolean isOpen=ProcessMonitor.isProcessOpen("Notepad.exe");
        System.out.println("Is Notepad open? "+isOpen);
    }
}

How to add?

You can copy the source code directly and change to your project, or you can add it as a dependency to your project(as a jar).
