An explanation and implementation of the Dijkstra Algorithm in Java. Dijkstra's Algorithm works on the basis that any subpath B -> D of the shortest path A -> D between vertices A and D is also the shortest path between vertices B and D.. Each subpath is the shortest path. Next, we introduce two commonly used shortest path algorithms: Dijkstra algorithm His algorithm idea is to merge step by step according to the increasing order of path length, which is an application of greedy algorithm to solve the shortest path problem from single source point to other vertices.
