compiler error in the Party.java on page 3

[Dinesh Kumar Tadepalli]

when i ran the party.java on page 3 of head first java, the compiler gave an error saying p.add(1) - cannot find symbol.

i also want to know if the letter inside the parenthesis of p.add is number 1 or capital letter I.

I tried both the ways but the compiler lists an error saying "cannot find symbol" and it points at p.add(1)

can anyone help me with this.

Please post the code. The "p" variable may be out of scope, or not even exist, but it's hard to tell without seeing the code.

Here is the code:

import java.awt.*;
import java.awt.event.*;
class Party{
public void buildInvite(){
Frame f = new Frame();
Label l = new Label("Party at Tim's");
Button b = new Button("You Bet");
Button c = new Button("Shoot me");
Panel p = new Panel();
p.add(1);
}
}

Thanks, waiting for your reply

  p.add(1);   

It should be,

  p.add(l);   

And please use code tags when posting code.

thanks for the correction.
Also, the program is giving other error stating.

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

What should I learn from this?

Also, the program is giving other error stating. " Exception in thread "main" java.lang.NoSuchMethodError: Main "

That's when you try to run the class which does not have a main method (in this case). Java look for a main method with the signature (public static void main(String[] args)) when you try to run a class using "java <classname>".
