java - 我们可以将包含 main 方法的类设为匿名吗

Question

下面是匿名内部类的示例，我们用 A 创建匿名类

class A
{
    void one()
    {
        System.out.println("hello");
    }
}

class One
{
    public static void main(String args[])
    {
        new A()
        {
            void five()
            {
                one();
            }
        }.five();
    }
}

我的问题是我们能否将类 One 设为匿名(不是其内部匿名类)，即包含 public static void main 方法的简单类。

Answer 1

static void main(String...) 必须是 static 并且内部类(匿名或其他)不能有静态方法。

关于嵌套类与内部类 http://docs.oracle.com/javase/tutorial/java/javaOO/nested.html

Nested classes are divided into two categories: static and non-static. Nested classes that are declared static are simply called static nested classes. Non-static nested classes are called inner classes.
