Scala entry-Eclipse Development Environment setup

Due to the need for deep learning, I recently started to learn Scala, an artistic programming language.

Scala: a java-like programming. Integrates the features of Object-Oriented (Oriented) programming and Functional (Functional programming) programming, which facilitates the development of multi-core concurrency models and cloud computing (parallelism for mulicore and cloud computing ).

For more information, see quick learning Scala. [for PDF download, see]. author: before installing Scala IDE, ensure that JDK is installed and environment variables are configured.

This is done in Windows 7.

Step 1: IDE download: Scala for Eclipse, http://scala-ide.org/download/sdk.html

Select a version and download it.

Step 2: Install scala2.11.1

After the scala-2.11.1.msi is downloaded, double-click to install. After installation, check whether the environment variables exist (if not, add the environment variables on your own ):

SCALA_HOME = D: \ Program Files (x86) \ scala (scala installation directory)

Path =... D: \ Program Files (x86) \ scala \ bin

In the console, enter scala-version to check whether the installation is successful. The following information is displayed.

Step 3: The first Scala Program

Start Eclipse, select its Workspace directory, and click File> New> Scala Project. Create a package: test. Create a Scala Object under the test package. For example, right-click run as --> scala application.

Console output: Hello World!
