"Scala beginner" Scala IDE eclipse

We talked about getting started with Scala, but after all, it's not like scripting language, and Scala is talking about replacing Java, so we'll see how he grabs the Java position.

A common editor for Scala, see below:

• Eclipse (using one of the shoddy and unstable Scala plugins)

• Emacs

• IntelliJ (basically just syntax highlighting support)

• TextMate

• Vim

• JEdit

Eclipse is not an effective combination with Maven, including SVN, which is gradually getting people thinking about other Ides, but this does not affect eclipse's beauty. I chose to use Eclipse as the IDE.

First step to install eclipse

Second step in Help->eclipse marketplace-> search scala-> Install Scala plugin (may need to restart Eclipse)

Step three Windows->open perspective-> Scala

Fourth step in the package Explorer right-click->new, Scala project

Fifth Step on SRC right click on New->package->demo.scala

Sixth step in package Demo.scala right New->scala Object (note here not Class)

Seventh Step

Write code:

def main (args:array[string]) = {println ("Hellowold")}

Eighth step

Right-click->run as->scala application

Attention:

Scala also has a way of running

Object Helloworld  extends application {println ("Hello, world!")}

Object Helloworld  extends App{println ("Hello, world!")}

These two ways can be used as one, you can directly run the function, do not need to write the Main method
