Title
Body
I want to launch a process from Java, read its output, and get its return code. But while it's executing, I want to be able to cancel it. I start out by launching the process: ProcessBuilder pb = new ProcessBuilder(args); pb.redirectErrorStream(true); Process proc = pb.start(); If I call proc.waitFor(), I can't do anything until the process exits. So I'm assuming I need to something like this: while (true) { see if process has exited capture some output from the process decide if I want to cancel it, and if so, cancel it sleep for a while } Is this right? Can someone give me an example of how to do this in Java?
