Class java.lang.Process

   +----java.lang.Process
public abstract class Process
extends Object
The exec methods return an instance of a subclass of Process that can be used to control the process and obtain information about it.

The subprocess is not killed when there are no more references to the Process object, but rather the subprocess continues executing asynchronously.
