    Unhappy NoSuchMethodError

    Ok, I have a main method, but it can't find it!

    I'm getting:

     

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




    My code is my really big program which I've posted several times. I'm worried that it's because more than one class in a package or a project might have a main method and it might be confused. Would that confuse it, having more than one class with a main method in the same package or project?

    I've no clue whatsoever.

    Default Re: NoSuchMethodError

    Are you sure the class you are trying to run has a main method?

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

    If it does? Paste the code here?!

    You can have as many classes as you want in the same package or project with a main method. How are you attempting to run your code?

    Hmmmmm.

    My main does throw some kind of exception as it needs to.

    Also, shat if one of my classes that I use as an object has a main method?

    I mean, if I have a class that extends JMenuBar and has a main method in the other class that also has a main method, the class that is throwing that error. Would that cause a problem?

    Yes it has a main.

    The code is too big to show. It's longer than the maximum amount of characters.

    I cut out some import statements and variable declarations, on the one that I posted, not my actual one, so it would fit.

    It's on the thread "What's going on?".

    JSourceCode might have a main method.

    Suppose it does.

    I will ask again, how are you attempting to run your code? (From an IDE such as eclipse? from the command line (java classNameWithMain)?)

    Ok if you are using eclipse, you should be able to right click in the class file that has the main method you want to run, and choose "run as java application"

    If this doesn't work, you probably have a problem with the way you declared your main.
