Hi all. I'm just starting to learn Java and Eclipse so write a simple program that print Hello World but when I try to get it run I get an error which is mention in the topic.

Source code:

package niewitaj;

public class NieWitaj {
	public static void main(String[] args){
System.out.println("Nie powiemy Witaj, w świecie!");}
}

In the Eclipse Package or Project Explorers, open your project and drill
down to the Java source you wrote. Right-click on it and choose Run Java
Application.

If you wish to run from the command line, you'll need to generate a JAR.
That's a couple of lessons from today. Run inside Eclipse for now.
