Example Code

MutableUndirectedUnweightedGraph<String> graph = MutableUndirectedUnweightedGraph.create();
graph.insertVertex("A");
graph.insertVertex("B");
graph.insertVertex("C");
graph.insertVertex("D");
graph.insertVertex("E");

graph.addEdge("A", "B");
graph.addEdge("D", "C");

int number = NumberOfConnectedComponents.calc(graph); // must be 3. {A,B}, {C,D}, {E}
