Methods inherited from class java.lang.Object clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait. Field Details. WebSummary. Dijkstra's algorithm is used to find the shortest distance between the nodes of a graph. We can use this algorithm for both directed and undirected graphs, but it won't work with negative edge weights. We can further optimize our implementation by using a min-heap or a priority queue to find the closest node.
