This is.

A Java regular expression, or Java regex, is a sequence of characters that specifies a pattern which can be searched for in a text. A regex defines a set of strings, usually united for a given purpose. Suppose you need a way to formalize and refer to all the strings that make up the format of an email address if it returns true, you know the string starts with the relevant pattern. Winston PS: As far as I know, you don't need both Pattern.CASE_INSENSITIVE and Pattern.UNICODE_CASE, and it may slow down your match. They basically do the same thing, so choose one (I'd go with the Unicode one myself; but you should test it to make sure)

Java has built-in API for working with regular expressions; it is located in java.util.regex. A regular expression defines a search pattern for strings. Pattern is a compiled representation of a regular expression.Matcher is an engine that interprets the pattern and performs match operations against an input string. Matcher has methods such as find(), matches(), end() to perform matching. Let's start with the simplest use case for a regex. As we noted earlier, when a regex is applied to a String, it may match zero or more times. The most basic form of pattern matching supported by the java.util.regex API is the match of a String literal. For example, if the regular expression is foo and the input String is foo, the match will succeed because the Strings are identical: @Test.
