I have written some java classes to generate a random network.
The network is made of : 200 nodes . Each node has a maximum of 50 neighbors.
What i want is to Randomly chose a node from that network and GRAPHICALLY show it with its one hop neighbors and its second hop neighbors.
I have these information saved in the code since each Node has 2 arraylists, one to save its one hop neighbors, and another to save it second hop neighbors. I have never used java to draw before, can you please tell me what classes i should use in order to get what i want ? thank you :)
