In addition to the core string handling methods just described, String defines several other methods Two that are quite commonly used are length( ), which returns the number of characters in a string, and charAt( ), which returns the character at a specified index For the most part, the recipes in this chapter use String, and it is usually your best choice when working with strings However, in those few cases in which you need a string that can be modified, Java offers two choices The first is StringBuffer, which has been a part of Java since the start It is similar to String except that it allows the contents of a string

to be changed Thus, it provides methods, such as setCharAt( ) and insert( ), that modify the string The second option is the newer StringBuilder, which was added to Java in version 15 It is similar to StringBuffer except that it is not thread-safe Thus, it is more efficient when multithreading is not used (In multithreaded applications, you must use StringBuffer because it is thread-safe) Both StringBuffer and StringBuilder are packaged in javalang
Java s Regular Expression API
Regular expressions are supported in Java by the Matcher and Pattern classes, which are packaged in javautilregex These classes work together You will use Pattern to define a regular expression You will match the pattern against another sequence using Matcher The precise procedures are described in the recipes that use them Regular expressions are also used by other parts of the Java API Perhaps most importantly, various methods in String, such as split( ) and matches( ), accept a regular expression as an argument Thus, often you will use a regular expression without explicitly using Pattern or Matcher Several of the recipes in this chapter make use of regular expressions Most do so through String methods, but three explicitly use Pattern and Matcher For detailed control over the matching process, it is often easier to use Pattern and Matcher In many cases, however, the regular expression functionality provided by String is both sufficient and more convenient Several methods that use regular expressions will throw a PatternSyntaxException when an attempt is made to use a syntactically incorrect regular expression This exception is defined by the regular expression API and is packaged in javautilregex You will need to handle this exception in a manner appropriate to your application
An Introduction to Regular Expressions
Before you can use regular expressions, you must understand how they are constructed If you are new to regular expressions, then this overview will help you get started Before continuing it is important to state that the topic of regular expressions is quite large In fact, entire books have been written about them It is well beyond the scope of this book to describe them in detail Instead, a brief introduction is given here that includes sufficient information for you to understand the examples in the recipes It will also let you begin experimenting with regular expressions of your own However, if you will be making extensive use of regular expressions, then you will need to study them in significantly more detail As the term is used here, a regular expression is a string of characters that describes a pattern A pattern will match any character sequence that fits the pattern Thus, a pattern constitutes a general form that will match a variety of specific sequences In conjunction with a regular expression engine (such as that provided by Java s regular expression API), a pattern can be used to search for matches in another character sequence It is this ability that gives regular expressions their power when manipulating strings A regular expression consists of one or more of the following: normal characters, character classes (sets of characters), the wildcard character, quantifiers, boundary matchers, operators, and groups Each is examined briefly here
