How to get a list of current open windows/process with Java?

by

This is another approach to parse the the process list from the command “ps -e“:

try {
    String line;
    Process p = Runtime.getRuntime().exec("ps -e");
    BufferedReader input =
            new BufferedReader(new InputStreamReader(p.getInputStream()));
    while ((line = input.readLine()) != null) {
        System.out.println(line); //<-- Parse data here.
    }
    input.close();
} catch (Exception err) {
    err.printStackTrace();
}

If you are using Windows, then you should change the line: “Process p = Runtime.getRun…” etc… (3rd line), for one that looks like this:

Process p = Runtime.getRuntime().exec
    (System.getenv("windir") +"\\system32\\"+"tasklist.exe");

Hope the info helps!
