How To know that subprocess still running

Hi,I ask for help of knowing if the process started by Runtime.getRuntime().exec is still running. I have 3 processes which I want to run one after another. each process has to start by envoking Runtime.getRuntime().exec after the previous one terminated.

Please read the API documentation for the Process class, it provides methods to manage and monitor the process that Runtime.exec returns.
