How do I get the return code in Java after executing a windows command line command

Question

I\'m doing something like this in Java right now

Process p = Runtime.getRuntime().exec(\"ping -n 1 -w 100 127.0.0.1\")

How can I read the w

Answer 1

next line of code:

int returnCode = p.waitFor();

This blocks until process is complete. You can also use the Process.exitValue() method, if you don't want to block. See Java6 Process class API doc
