用 eclipse 写 Java 代码时出现了这个问题，详细如下：

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

其中 A 为类名。

原因：原来是静态方法中不能创建动态内部类的对象。

解决方法：将类改为 static, 或将方法改为非静态的。
