- Method Detail
  - containsSelfEdges
```
public static <V,E> boolean containsSelfEdges(Graph<V,E> g)
```
    Check whether a graph contain self edges.
    A self edge is an edge whose source and target is the same vertex.
    
    Type Parameters:
    
    V - the vertices type
    
    E - the edges type
    
    Parameters:
    
    g - a graph
    
    Returns:
    
    true if the graph contain at least one self edge, else false
  - containsParallelEdges
```
public static <V,E> boolean containsParallelEdges(Graph<V,E> g)
```
    Check whether a graph contain parallel edges.
    Two parallel edges are edges that have the same source and target vertices.
    
    Type Parameters:
    
    V - the vertices type
    
    E - the edges type
    
    Parameters:
    
    g - a graph
    
    Returns:
    
    true if the graph contain at least one pair of parallel edges, else false
