基于Java的最短路径的算法实现与演示

Java-based Shortest Path Algorithm Application and Demonstration

面向对象框架是一种大型的面向对象复用技术，它兼有设计复用和代码复用的优势，为基于复用的软件开发提供了一种强有力的工具。JHotDraw便是这样一个著名的例子，它是用来简化绘图应用程序的可高度定制化的GUI框架。本文将通过JHotDraw中应用的几个重要设计模式来解JHotDraw框架及框架的基本原理。

Object-oriented framework is a large-scale software reuse technique.It has the advantages of both design reuse and code reuse,providing a powerful tool for software development based on software reuse.A well-known example of this is JHotDraw, a highly customizable GUI framework that simplifies developing drawing applications.This article explains the JHotDraw framework and general framework principles in terms of several important design mode.
