Is it possible to force Java to throw an Exception after some block of code runs longer than acceptable?

Question

I have a block of code, while executing code it will generate popup window, if we click manually then it will process, because of that it is waiting long time, I Would like to introduce timeout function here, can suggest please?

try {
        Process process = Runtime.getRuntime();
        process.waitFor(); //need to introduce Timeout here.
        returnValue = process.exitValue();
        if (returnValue != -1) {
        return true;
        }
    } catch (Exception e) {
        System.out.println(e);
        return false;

if didnt get response within time frame then forget it, and it should return false.

Use Process.waitFor(long,TimeUnit).

Causes the current thread to wait, if necessary, until the subprocess represented by this Process object has terminated, or the specified waiting time elapses.
