In java determine if a process created using Runtime environment has finished execution?

Question

Runtime.getRuntime.exex(\"abc.exe -parameters\");

using .waitFor() does not help to determine the completion of process.

Answer 1

I have a similar issue and neither of the methods written here works for me. This is my code:

public void startCCleaner() {
    System.out.println("Starting ccleaner...");
    try {
        Process process = new ProcessBuilder("C:\\Program Files\\CCleaner\\CCleaner64.exe").start();
        if(process.waitFor() == 0 ){
            System.out.println("Process terminated ");
        }
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}
