Java’s character and assorted string classes offer low-level support for pattern matching, but that support typically leads to complex code. For simpler and more efficient coding, Java offers the Regex API. This two-part tutorial helps you get started with regular expressions and the Regex API. First we’ll unpack the three powerful classes residing in the java.util.regex<\/code> package, then we’ll explore the Pattern<\/code> class and its sophisticated pattern-matching constructs.<\/p>\n

A regular expression<\/em>, also known as a regex<\/em> or regexp<\/em>, is a string whose pattern<\/em> (template) describes a set of strings. The pattern determines which strings belong to the set. A pattern consists of literal characters and metacharacters<\/em>, which are characters that have special meaning instead of a literal meaning.<\/p>\n
