Examples of java.lang.Process.waitFor()

java.lang.Process.waitFor()
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. @return the exit value of the process. By convention, 0 indicates normal termination. @exception InterruptedException if the current thread is {@linkplain Thread#interrupt() interrupted} by anotherthread while it is waiting, then the wait is ended and an {@link InterruptedException} is thrown.
