Thank you, Owen. I should have figured that out. I was thinking too
much and confused myself.
What is a callback?

Subclass ByteArrayOutputStream and override the write() methods (there
are two).
e.g. (partial, not tested):
class myByteArrayOutputStream extends ByteArrayOutputStream {
...
public void write(int b) {
super.write(b);
// do my stuff
}
...
}
Add callbacks if you need to.

I'm reading the docs but coming up short. I want to send an email
when I get a message posted to System.out or System.err. So far, I
have ...
// none of this has been tested yet
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintStream ps = new PrintStream(baos);
System.setOut(ps);
System.setErr(ps);
I can do baos.toString() to get the String I need for the body of the
email. The problem is that when my ByteArrayOutputStream baos gets
written to, I need to do stuff, then send the email.
I can't figure out a way to set off another method after baos gets
data. Any ideas?
Thank you,
Nathan
