how to compile in netbeans...i just downloaded it

As per instruction from my previous thread, I downloaded netbeans IDE but now I don't know how to start off. Where I shall write code and how to compile code? In netbeans, I clicked File >> New Project >> JAVA Application >> there it has some templates with words like public static void main....I wrote "System.out.println ("Hello World!)" but now how to view outpu?

Basically I want to write this basic code in netbeans to start off

class HelloWorld {
public static void main(String[] args)
{
System.out.println("Hello World!");
}
}
