#Scala language code

Scala has a set of features that completely differ from Java. It allows you to write codes in an immutable manner, which makes it easy to apply concurrency and parallelism (Synchronize).

#Scala language code

It reduces the number of lines and helps the programmer to code in a type-safe way. Scala allows you to express general programming patterns in an effective way. Scala was designed to improve upon Java, so you can call Java methods, inherit from Java classes, and more. The name is an acronym from Scalable Language. Scala can do Concurrent & Synchronize processing The Scala programming language was created in 2001 by Martin Odersky to combine functional programming and object-oriented programming into one language.

Scala enables you to use all the classes of the Java SDK and also your own custom Java classes, or your favorite Java open source projects. The ' scala' command is similar to the java command, in that it executes your compiled Scala code. ScalaFiddle is integrated with some of the code examples in this documentation if you see a Run button in a code example below, click it to. The Scala compiler compiles your Scala code into Java Byte Code, which can then be executed by the ' scala' command. This is an easy, zero-setup way to experiment with pieces of Scala code: Go to Paste println ('Hello, world') in the left pane. This means that Scala and Java have a common runtime platform. Scala is compiled into Java Byte Code which is executed by the Java Virtual Machine (JVM). You don't have to specify a type in most cases, and you certainly don't have to repeat it. Scala, unlike some of the other statically typed languages (C, Pascal, Rust, etc.), does not expect you to provide redundant type information. These concepts will be explained in subsequent chapters. Scala provides a lightweight syntax for defining anonymous functions, it supports higher-order functions, it allows functions to be nested, and supports currying. Scala is also a functional language in the sense that every function is a value and every value is an object so ultimately every function is an object. Types and behavior of objects are described by classes and traits which will be explained in subsequent chapters.Д¬lasses are extended by subclassing and a flexible mixin-based composition mechanism as a clean replacement for multiple inheritance. Both the Scala compiler and interpreter can. Everything you type gets compiled to the byte code, and then it runs within the JVM.Scala possesses much different from other languages which are interpreted.

Arguably, Scala can both be interpreted and compiled. Scala is a pure object-oriented language in the sense that every value is an object. Scala usually has an illusion of an interpreted language, but it is a compiled language. Here we have presented a few points that makes Scala the first choice of application developers. Many existing companies, who depend on Java for business critical applications, are turning to Scala to boost their development productivity, applications scalability and overall reliability. Scala is compiled to run on the Java Virtual Machine. Scala smoothly integrates the features of object-oriented and functional languages. Scala, short for Scalable Language, is a hybrid functional programming language.
