java - 选择不包含主要类型

Question

每当我想运行程序时，我都会遇到上述错误，使用 Eclipse 所以基本上我在使用 boolean 任何解决方案时尝试了几乎所有内容

package class;

public class My {
    public  boolean sleep In(boolean weekday, boolean vacation) {
          if (!weekday || vacation) {
            return true;
          }

          return false;
    }
}

Answer 1

Java应用程序需要一个main方法作为入口点。因此，添加一个 main 方法并开始执行程序。主要方法签名为:

public static void main(String[] args)

The modifiers public and static can be written in either order (public static or static public), but the convention is to use public static as shown above. You can name the argument anything you want, but most programmers choose "args" or "argv".
