Reason One
In a class/interface of inheritance (extends)/implementation (implements), other jars on which this class/interface depends cannot be relied upon or referenced in this class.
Example: Class A Inheritance (extends) class B, import the Com.jixue.dna.ui.portal.TaskUtil class in Class B, and Class A is not dependent on the Com.jixue.dna.ui.portal.jar package, so error.

D is the distance matrix.
Method represents the merging methods of the class, which are:
Single Shortest distance method
Complete the longest distance method

A few days ago to see the "the Guru's Guide to Transact SQL" (Chinese translation is a Transact-SQL authoritative guide), which describes a query is about the hierarchy, the way to deal with the nature of the queue, traversal of the result is like traversing the binary tree in the first sequence traversal, very interesting.
The table structure to be queried is as follows:
Each layer node assigns a unique ID, the name of the node, and the ID of the
