GabowStrongConnectivityInspector<V,E> 
Computes the strongly connected components of a directed graph.

KosarajuStrongConnectivityInspector<V,E> 
Computes strongly connected components of a directed graph.

A directed graph is called weakly connected if replacing all of its directed edges with undirected edges produces a connected (undirected) graph. It is strongly connected if it contains a directed path from $u$ to $v$ and a directed path from $v$ to $u$ for every pair of vertices $u$, $v$. The strong components are the maximal strongly connected subgraphs.
