eclipse提示No enclosing instance of type Constructor is accessible

学习JAVA中构造方法的使用，输入如下程序：

public class Constructor {
public static void main(String[] args)
{
   Person p=new Person(12);
   p.show("JAVA构造方法演示");
}
class Person
{
   public Person(int x)
   {
   a=x;
   System.out.println("构造方法被调用");
   System.out.println("a="+a);
}
public void show(String msg)
{
   System.out.println(msg);
}
private int a;
}}

运行后在红色字体处系统提示：

No enclosing instance of type Constructor is accessible. Must qualify the allocation with an enclosing instance of type Constructor
(e.g. x.new A() where x is an instance of Constructor).

无访问类型构造的封装实例，必须分配类型构造的封装实例。

因此将程序修改如下：

public class Constructor {
public static void main(String[] args)
{
   Constructor pi=new Constructor();
   Constructor.Person p=pi.new Person(12);
   //Person p=new Person(12);
   p.show("JAVA构造方法演示");
}
class Person
{
   public Person(int x)
   {
   a=x;
   System.out.println("构造方法被调用");
   System.out.println("a="+a);
}
public void show(String msg)
{
   System.out.println(msg);
}
private int a;
}}

这一段在书上并未明确，不知这样理解是否正确。
