When Java runs a subprocess with one of the Runtime exec() methods, 
it pipes the standard streams for the process back to the Java VM.  
You can use the Process object returned from the exec() method to 
write to the process's input stream and read from its output and 
error streams.

Note that since there are two different streams to be read, you have 
to create threads to do this.  And if there is any chance that the 
process will produce output, ignoring this could cause the process to 
hang.  Exactly when this will happen is system dependant, since it 
depends on the buffering of those pipes.
