我的主要课程（命名为＆＃34;组件）有public static void main(String args[]) {，我用它来打开主菜单。
public static void main(String args[]) {
Component component = new Component();
new Menu(component);
}
这会导致您在运行游戏后立即显示主菜单屏幕。
在主菜单中按一个按钮后，它将使用component.start();
问题是我无法在Menu类中调用render方法，因为它是运行程序时首先打开的方法
抱歉，如果它令人困惑。如果您需要任何其他信息，请与我们联系。感谢
