Chapter 13. Strings and Regular Expressions
What's the use of a good quotation if you can't change it?

Strings are standard objects with built-in language support. You have
already seen many examples of using string literals to create string ob-
jects. You've also seen the
+
and
+=
operators that concatenate strings to
create new strings. The
String
class, however, has much more function-
ality to offer.
String
objects are immutable (read-only), so you also have
a
StringBuilder
class for mutable strings. This chapter describes
String
and
StringBuilder
and some related classes, including utilities for regular
expression matching.
