"WebThere are multiple ways to implement DFS in Java. We will be using an adjacency list for the representation of the graph and will be covering both recursive as well as an iterative approach for implementation of the algorithm. The graph used for the demonstration of the code will be the same as the one used for the above example. " - Dfs using iteration
