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

Question

Does any one know how do I get the current open windows or process of a local machine using Java?

What I'm trying to do is: list the current open task, windows or process open, like in Windows Taskmanager, but using a multi-platform approach - using only Java if it's possible.

Answer 1

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!
