Question

I executed a batch file from within my Java code like below:

Runtime.getRuntime().exec("cmd /c start update.bat");

I want to know whether can I get any notification when this batch script completes. Is it possible?

Regards,

Answer 1

Keep a reference to the Process and waitFor the process to stop, this will halt your excecution.

 Process proc = Runtime.getRuntime().exec("cmd /c start update.bat");
 int exitVal = proc.waitFor();

Do as the good example in this link (When Runtime.exec() won’t). If you read the whole article you will avoid and understand many pitfalls of the exec command.

Then you can read up on ProcessBuilder which is a more modern way to invoke other processes.
