Scala is a general-purpose programming language—a language that is designed for solving all kinds of problems, not just a specific one.^[1]

It provides support for functional programming, and is statically typed. It is designed to fix some problems with Java,^[2] and to be concise—to be able to express a lot with only a little bit of code.^[3]

Scala code is supposed to be compiled into Java bytecode, so Scala code can be run on a Java Virtual Machine (JVM). Scala has language interoperability with Java—Scala code can be used in Java programs, and the other way around.^[4]

Examples

"Hello, World" example

This is a small example of a Scala program. A simple Hello world program:

@main def main() = println("Hello, World!")
