The class System has a variable out that represents the
standard output, and the variable err that represents the
standard error device. By default, they both point at the
system console. This how the standard output could be re-
directed:

Stream st = new Stream(new FileOutputStream("output.txt"));
System.setErr(st);
System.setOut(st);
