Overview Of Scala Programming Language- How To Install Scala ?

SCALA (Scalable Language)  is a modern programming language created by Martin Odersky , influenced by Java, Ruby, Smalltalk and others.

Scala smoothly and effortlessly integrates object-oriented and functional programming .It supports Java-like superior coding style and simultaneously supports a functional style.

Combining the strengths of the Functional and Imperative programming models, Scala is a great tool for building highly concurrent applications without surrendering the advantages of an OO methodology. 


Features of Scala Programming Language
  • Scala code runs on the JVM and allows you to use the affluence of Java libraries that have been developed over the years.
  • Features in object oriented programming (OOP) language such as Classes and inheritance are fully supported in Scala. Some other features in Scala are traits, objects and case classes.
  • Every variable here is an object (Variable definitions start with var ) and every “operator” is a method. It’s also has functional programming (FP) language, so you can pass functions (Function definitions start with def.) around as variables.
  • Scala has advanced language features and rich Java integration.You can write your Scala code using OOP, FP, or both.  
  • Scala has expressive syntax and static typing


Installing Scala Software
For Installing Scala On Unix systems download the software from the Scala download page to a directory on your computer like $HOME/scala, and then add these lines to your $HOME/.bash_profile file.
export SCALA_HOME=/Users/Al/scala
PATH=$PATH:/Users/Al/scala/bin

To Install Scala in Microsoft Windows you can follow equivalent process. Check the Scala download page for more information.
