Scala runs on the Java platform (Java virtual machine) and is compatible with existing Java programs. [15] As Android applications are typically written in Java and translated from Java bytecode into Dalvik bytecode (which may be further translated to native machine code during installation) when packaged, Scala's Java compatibility makes it well-suited to Android development, the more so when ...
Map functions can be and often are defined in terms of a fold such as foldr, which means one can do a map-fold fusion: foldr f z . map g is equivalent to foldr (f . g) z . The implementation of map above on singly linked lists is not tail-recursive , so it may build up a lot of frames on the stack when called with a large list.

sbt is the de facto build tool in the Scala community, [6] used, for example, by the Scala 2 and Scala 3 compilers themselves, [7] [8] Play Framework, and Lichess, a popular chess server. The sbt project is "bootstrapped" — it uses sbt to build itself and considers dogfooding a positive feature.
ECLAIR – Uses formal methods-based static code analysis techniques such as abstract interpretation and model checking combined with constraint satisfaction techniques to detect or prove the absence of certain run time errors in source code. ESC/Java and ESC/Java2 – Based on Java Modeling Language, an enriched version of Java
Kojo is a programming language and integrated development environment (IDE) for computer programming and learning. It has many different features that enable playing, exploring, creating, and learning in the areas of computer programming, mental skills, (interactive) math, graphics, art, music, science, animation, games, and electronics.
A singleton implementation may use lazy initialization in which the instance is created when the static method is first invoked. In multithreaded programs, this can cause race conditions that result in the creation of multiple instances. The following Java 5+ example [6] is a thread-safe implementation, using lazy initialization with double ...
