Hi Susan -- I am thrilled you are looking at this problem. Besides
ProcessBuilder, Process and Runtime, what other classes are there in java6
that would implement the methods correctly?
ProcessBuilder I believe was a public final class, so it can't be
subclassed.
Thanks.

Subject: [brailleblaster] Java varargs
After staring at the ProcessBuilder javadoc for a while, I realized there
was something I didn't recognize which turns out to be a vararg, introduced
in Java 5. Only the final (or single parameter) of a method may be a vararg.
The snytax is the type followed by three periods followed by the name, e.g.
String ... command. A vararg may be passed either as an array or as a
sequence of arguments. So ProcessBuilder can accept a String array as an
argument. (Although, per my previous post, direct use of ProcessBuilder may
not be want we want to do.)
