# Warshall’s algorithm

Lab 6 Implement Warshall’s algorithm to find the transitive closure for a graph. class WarshallApp { public static void main(String[] args) throws IOException { Graph theGraph = new Graph(); theGraph.addVertex('A'); // 0 theGraph.addVertex('B'); // 1 theGraph.addVertex('C'); // 2 theGraph.addVertex('D'); // 3 theGraph.addVertex('E'); // 4 theGraph.addEdge(0, 2); // AC theGraph.addEdge(1, 0); // BA theGraph.addEdge(1, 4); // BE theGraph.addEdge(3, 4); // DE theGraph.addEdge(4, 2); // EC System.out.println("Original adjacency matrix"); theGraph.adjMatDisplay(); // display adj matrix theGraph.warshall(); // do the algorithm System.out.println(); } } If you are using the above codes in your solution, the output will looks like: Original adjacency matrix A B C D E ==================== A 0 0 1 0 0 B 1 0 0 0 1 C 0 0 0 0 0 D 0 0 0 0 1 E 0 0 1 0 0 Transitive closure A B C D E ==================== A 0 0 1 0 0 B 1 0 1 0 1 C 0 0 0 0 0 D 0 0 1 0 1 E 0 0 1 0 0
