title: Need a Hello World example in IntelliJ IDEA
body: <p>In Eclipse, it's easy, I just need to add a class and tick into something like <code>Add public static void main()</code> then run. But with IntelliJ IDEA I can't find how to create a simple "Hello World" project, the run button (<kbd>Shift</kbd> + <kbd>F10</kbd>) is always grayed out even after I added a main class in <code>Edit Configurations</code>. In fact, my JAVA background is not good and I am also a newbie to IntelliJ IDEA. So I am thankful to someone who show me a way to start.  </p>
  
  <p>Thank in advance.</p>
  
  <p>p/s : I started with a Java Module project, import JDK 6.0, I didn't choose any technology. Then I created a package and a class under <code>src\</code>. I saw a TUT video on youtube that there even has a make <code>main()</code> command with right click on the class name but I can't find it anywhere. I am using IntelliJ IDEA 11 in 30 days evaluation.</p>
