Implementing DFS in Java Depth First Search Algorithm

WebDepth First Search can be used to search in Tree or Graph. Traversals of both Graph and Tree are almost similar but the only catch is that Graphs contains cycles and nodes, and node can be visited twice. DFS uses stack as a data structure and process or algorithm is similar to BFS algorithm.
