Void
The Void class has one field, TYPE, which holds a reference to the Class object for type void.
You do not create instances of this class.
Process
The abstract Process class encapsulates a process--that is, an executing program. It is used

by start( ) in the ProcessBuilder class. Process contains the abstract methods shown in
Table 16-10.

InputStream getErrorStream( )
Returns an input stream that reads input from the process'
err output stream.
InputStream getInputStream( )
Returns an input stream that reads input from the process'
out output stream.
OutputStream getOutputStream( )
Returns an output stream that writes output to the process'
