问题描述：

用JAVA帮我画个简单的拓扑图，图形如图所示，要用java实现，麻烦写出代码，采用的话追加高分，谢谢

如果可以的话，帮我在图上随机生成参数，链路的参数(1~10)，节点上2个参数，也是1~10

我要用这些参数来计算，最后生成一条路径。

生成的路径最好是动态生成的。

能做多少是多少，必有重谢！

Q-5369248

那个图我自己会画了，请教一下，在Eclipse里怎么关联两个JAVA程序？

先显示这个图，然后显示另外一个有路径的图(在此图基础上有一段路径加粗)。

在同一个窗口或者不在都行

解决方法：

如果需要的话留个邮箱，我把程序发给你。

晕~~我索性写个最短路径的给你吧，等着~
