- Method Detail
  - addEdge
```
boolean addEdge(int begin,
                int end)
```
    Adds an unweighted edge between two vertices. In an undirected graph, this has the same effect as addEdge(end, begin).
    
    Returns:
    
    false if the edge was already in the graph.
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if either vertex ID is out of bounds.
