How to set the main class to be run first

I have main class, login class and mainmenu class and they are all in a same package name Myapp. When I run Myapp its listing all these three classe and asking me to select the main class.
Is there a way I can set up so that by running Myapp, it will execute the main class first without having me select from the list?
I am building this application using NetBeans and Swing

Any help would be really appreciated.

You need main method in Main class

public static void main(String[] args) {\

I do have that.
Also just want  to point out that my login class also has main method. So should I only have main method in my Main Class. If that the case then how can I call my login class from my main class so it will execute from main class?

Have one.

You will need to call some method of Login class.

In that case I should take out the main method from login class and add some method in my main class to call login class - correct?
Would you happen to have some sample code as a guide.

Thanks so much for your help.
See the example. You could put your "main" login code in a constructor of Login class too. It will be executed at new Login().
public class Main {

  Login login;

  public static void main(String[] args) {
    login = new Login();

class Login {
  loginMainMethod() {

In your above sample, class Login portion of the codes, should it be in my Login class? Or in my Main Class?
In my Login class I have SubmitButtonActionPerformed where I connect to the database based  on user/password.

Thanks so much.

NetBeans only do this if you did not select your main class. After you've selected your main class for this project NetBeans will no longer ask again if the project was saved after you've selected the main class. The main class is always the one with the main method in it because that is where all java programs starting point is.
