WebImplement Graph Using Map - Java. Earlier, we have seen Graph and its representation s. A graph can be represented using adjacency list and adjacency matrix. So far we have seen the traditional implementation of the Graph. In this article, we will implement the Graph represented by Adjacency List using the HashMap data structure. WebBasically, Graphs are best implemented with the help of HASHING and the above datastructure helps a lot in that.. This is not true, hashing isn't always best, sometimes an Adjacency Matrix is the best structure. It depends on the algorithm. Also, not all maps use Hashing, for example TreeMap doesn't.
