What's the use of a good quotation if you can't change it?
|--Dr. Who, The Two Doctors|
Strings are standard objects with built-in language support. You have already seen many examples of using string literals to create string objects. You've also seen the
+= operators that concatenate strings to create new strings. The
String class, however, has much more functionality to offer.
String objects are immutable (read-only), so you also have a
StringBuilder class for mutable strings. This chapter describes
StringBuilder and some related classes, including utilities for regular expression matching.
