用JAVA画个简单的拓扑图

https://zhidao.baidu.com/question/151408808.html?qbl=relate_question_0&word=%D3%C3Java%BB%E6%D6%C6%BD%DA%B5%E3%D6%AE%BC%E4%B5%C4%CD%BC

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~
