Question

I have to run a bat file in a loop in my java code. it means when a process finish for a file another process start after that. I ma using Thread.sleep in my project after calling process bat file. but the problem is I don’t know how a bat file does it take, for some file it takes 1 hour for some of them takes 10 minutes. how can i understand when a process will be finished ?

Answer 1

If you run it by creating a Process with Runtime.getRuntime().exec(), you can call the waitFor() method on the Process to wait for it to exit.

Using Process.exitValue() you can even read error levels that the .bat files might return.
