Get an overview of regular expressions.
- [Narrator] Regular expressions are a…pattern matching technique.…The technique uses strings that consist of…metacharacters, which have special meaning…and regular characters, which have a literal meaning.…Regular expressions derive from a branch of computer science…known as Formal Language Theory.…Regular expressions have a formal mathematical definition…and an implementation-specific definition…within computer languages.…In this course we will not use the…formal mathematical definition.…
We will use the java language-specific definition.…This slide lists several sources…for learning more about regular expressions.…Most search engines have the facility…for using regular expressions, and many text editors…have the facility within the find and replace capabilities.…You can find out more about using regular expressions…within IntelliJ by navigating to this URL.…Java has two broad categories of support…for regular expressions.…
Methods within the string class…plus the pattern and matcher classes.…We'll cover both within this chapter.…
