No enclosing instance of type Actor is accessible. Must qualify the allocation with an enclosing instance of type Actor (e.g. x.new A() where x is an instance of Actor).
static 的作用，就是共享且类唯一，如果一个类要被声明为static的，只有一种情况，就是静态内部类
哪位大神帮帮忙？？？？
我是把 class Actress()直接写到main方法的下面了，也出现了这种错误，我并没有写在Actor的里面
Actress类应该被定义在Actor类的里边了, 也就是说Actress被弄成Actor的内部类了,把Actress类的代码复制到Actor外边
public class Actor(){
}
class Actress(){
}
或者new Actress()改为new Actor.Actress()就可以了.
