Do you know the syntax of Java's regular expressions? See <http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html>. In short, anything contained within square brackets is considered to be a set of characters to match on, so [true|t] succeeds if the character it's matching against is a t, r, u, e, or |. The syntax you probably wanted was (true|t), which would either match the string "true" or the string "t". -- Beware of bugs in the above code; I have only proved it correct, not tried it. -- Donald E.
