Hi,

fhe javadoc for java.lang.Process states:

waitFor

public abstract int waitFor() throws InterruptedException

causes the current thread to wait, if necessary, until the process represented by this Process object has terminated. This method returns immediately if the subprocess has already terminated. If the subprocess has not yet terminated, the calling thread will be blocked until the subprocess exits.

Returns: the exit value of the process. By convention, 0 indicates normal termination.

Throws: InterruptedException if the current thread is interrupted by another thread while it is waiting, then the wait is ended and an InterruptedException is thrown.

I think that this answer your question.
