Scala is a general-purpose programming language principally targeting the Java Virtual Machine. Designed to express common programming patterns in a concise, elegant, and type-safe way, it fuses both imperative and functional programming styles. Its key features are: an advanced static type system with type inference; function types; pattern-matching; implicit parameters and conversions; operator overloading; full interoperability with Java; concurrency

 

Programming in Scala: Since the Scala is a lot similar to other widely used languages syntactically, it is easier to code and learn in Scala. Programs can be written in Scala in any of the widely used text editors like Notepad++, gedit etc. or on any of the text-editors. After writing the program, save the file with the extension .sc or .scala.

For Windows & Linux: Before installing the Scala on Windows or Linux, you must have Java Development Kit(JDK) 1.8 or greater installed on your system. Because Scala always runs on Java 1.8 or above.
