running an Executable file and then waiting for that particular exe file to no longer be running

I want to run a vb generated exe file from java and wait for the file to finish execution.

I tried to use p.waitFor() but with no success.

Is there any other alternative ?

Answer 1

This should actually work:

Runtime.getRuntime().exec(<file.exe>).waitfor();

Unless stdin/stdout of the Subprocess are involved then you could get in Deadlocks:

The JDK’s Javadoc documentation provides following information:

some native platforms only provide limited buffer size for standard
input and output streams, failure to promptly write the input stream
or read the output stream of the subprocess may cause the subprocess
to block, and even deadlock.

This is good explained here
