Graph with adjacency list java
WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time.
