    Default Failed to compile, Main Method Not found, assistance please.

    class DrumKit {

    boolean topHat = true;
    boolean snare = true;

    void playTopHat() {
    System.out.println("ding ding da-ding");
    }
    void playSnare() {
    System.out.println("bang bang ba-bang");
    }


    class DrumKitTestDrive {
    public static void main(String [] asrgs) {

    DrumKit d = new DrumKit();
    d.playSnare();
    d.snare = false;
    d.playTopHat();

    if (d.snare == true) {
    d.playSnare();
    }
    }
    }
    }

    --- Update ---

    This code was taken directly from an activity in the headfirst java book, when run through geany, it says that I am not allowed to have a static inside and inner class??

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    Please post your code correctly using code or highlight tags per the above link.

    The main() method must be in a top-level public class of the same name as the file in which the source code is stored.

    I suspect that these two classes are not intended to be in the same file/compilation unit. Split DrumKit and DrumKitTestDrive into their own files in the same directory. Or modify the file so the inner reference is properly referenced in a static manner from the static outer reference. Or make sure main() is declared in the top-level type.

    This is a fancy way of saying that if this is out of a book exactly as you show here, and it is supposed to compile, then the book has bugs. If this is a way to illustrate static and non-static refs to inner and outer classes, then it needs to be tweaked a little to achieve that.

    You have to close the DrumKit class first before starting DrumKitTestDrive i.e. } is missing before the DrumKitTestDrive class starts and remove the last } in the end.
