Exit value from java.lang.Process#waitFor()

Question

The method waitFor() returns an integer value which is the return code. The value 0 indicates normal termination. But what are the meanings of other return codes? I am getting an exit value 11. What does that mean? And where all the exit value codes are documented?

Answer 1

These values are arbitrary and up to the specific program to define. You should refer to documentation or source code of the program that is outputting this exit code.
