Java pattern matching library. Many languages support pattern matching at the language level. Java language does not support at the moment pattern matching but there is hope that in the future everything will be change. Using Java 8 features, we can emulate some of the features pattern match...
Pattern matching in the Java programming language is now as flexible as in many other programming languages. Regular expressions can be put to use in applications to ensure data is formatted correctly before being entered into a database, or sent to some other part of an application, and they ...
Following the goals of Project Amber, String Templates aims to make the Java programming language more readable, writable, and maintainable. JEP 440: Record Patterns JEP Goals: Enhances the Java programming language by extending pattern matching to destructure instances of record classes, enabling mor...
We’d like developers to create better code than that. We already have a feature in the Java language to allow for a multiplace conditional, that is,switch. The next natural location for us to enhance pattern matching is theswitchstatement. ...

It is an error to use a backslash prior to any alphabetic character that does not denote an escaped construct; these are reserved for future extensions to the regular-expression language. A backslash may be used prior to a non-alphabetic character regardless of whether that character is part of...
One good way to think of regular expressions is as a “little language” for matching patterns of characters in text contained in strings. Give yourself extra points if you’ve already recognized this as the design pattern known as Interpreter. A regular expression API is an interpreter for mat...
