Exception in thread "main" java.lang.NoSuchMethodError: main

[Joop Hey]

I'm reading the book "Head First Java" and have difficulties with some code:
import java.awt.*;
import java.awt.event.*;
class Party {

public void buildlnvite() {
Frame f = new Frame();
Label l = new Label("Party at Tim's");
Button b = new Button("You bet");
Button c = new Button("Schoot me");
Panel p = new Panel();
p.add(l);

}
}
Could someone explain the exception?
Thanks

Hello,
Sounds like you're trying to run your Party class without a main method. The main method is what the JVM uses to start off running a java program and every Java Program has a main method somewhere. The JVM requires it to have the following method signature:

public static void main(String[] args)

So you might try the following:

public static void main(String[] args)
{
     Party p = new Party();
     p.buildInvite();
}

Luck.

This is not a Servlets question, but a Java in General (Beginner) question. I am going to move this thread to the more appropriate forum.
