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

If you don't want to use waitFor(), which apparently you don't you can always test the exit value directly.

import java.util.*;
import java.io.*;
public class ProcExitTest
{
    public static void main(String args[])
    {
        try
        {            
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("<....>");
            int exitVal = proc.exitValue();
            System.out.println("Process exitValue: " + exitVal);
        } 
          catch (InterruptedException ie)
          {
            ie.printStackTrace();
          }
    }
}

exit code 0 means normal termination.
