Hello world doesn't run in IntelliJ Idea

I am newbe for IntelliJ idea, so I try from HelloWorld:

 package test;

 /**
  * Created with IntelliJ IDEA.
  * Date: 16/06/12
  * Time: 12:13
  * To change this template use File | Settings | File Templates.
  */
 public class Main {
     public static void main(String ...args){
        System.out.println("Hello World");
     }
 }

But this program doesn't run! Only green arrow getting grey, but I don't see any output. Which setting I should check? Thanks. Compiler:

Answer 1

Right click on the main function name and select Debug

The "green arrow" just runs the current configuration, when the above right clicking creates such. You can create and customize the configurations with the Edit Configurations button, to the left.

Answer 2

I found the reason - folder .IdeaIC was installed in my home directory that on network disk. After I have changed in properties ides.properties to use folder on local disk - all run well!
