JAVA:java可以检测其他正在打开的第三方应用程序吗

Question

我想设计一个在另一个第三方应用程序运行时运行的程序。例如，我想在 Skype 窗口打开时继续循环程序。这可能吗？

public class test {
    public static void main(String[] args) throws AWTException, InterruptedException {
        Robot robot = new Robot();
        int right = InputEvent.BUTTON3_DOWN_MASK;
        int left = InputEvent.BUTTON1_DOWN_MASK;

        TimeUnit.SECONDS.sleep(3);
        robot.mouseMove(1720, 960);  
        robot.mousePress(right);
        TimeUnit.SECONDS.sleep(1);
        robot.mouseRelease(right);
}

我想在 Skype 窗口打开时循环此代码。

您可以尝试类似的操作来查看哪些应用程序仍在运行；

String line = "";
Process proc = Runtime.getRuntime().exec("tasklist.exe");
BufferedReader input = new BufferedReader(
        new InputStreamReader(proc.getInputStream()));
while ((line=input.readLine()) != null) {
    // now you can do what you want e.g: you can check the line if contains skype application name or other skype belongings information.
    System.out.println(line);
}
input.close();

该程序的输出是:

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
Skype.exe                     9492 Console                    1    231,608 K
...

所以在while-loop中你可以检查

if(line.toLowerCase().contains("skype")) {
    // do what you want if skype is running
} else {
    // do what you want if skype is not running
}

希望这有帮助!
