Questions tagged [processbuilder]

Processbuilder is Java wrapper around an Operating System Process. This class is used to create operating system processes.

From the Javadoc:

Each ProcessBuilder instance manages a collection of process attributes. The start() method creates a new Process instance with those attributes. The start() method can be invoked repeatedly from the same instance to create new subprocesses with identical or related attributes.
