Prim's algorithm Java
Prim's algorithm in Java is one of the most used algorithms for Minimum Spanning Tree. Prim's algorithm starts with a spanning tree having no vertices. In prim's algorithm, we maintain two sets of vertices in which first contains those vertices that are present in the MSP and the second one contains those vertices that are not present in the MSP.
At each step, it considers all edges that combine the two sets and selects the minimum weight edge from these edges. After selecting an edge, it sets the other end of the edge that contains the MST.
Note: In order to update the key-value of the adjacent vertices v, if the weight of edge u-v is less than the previous key value of v, change the key value as the weight of u-v.
Let's implement the code of Prim's algorithm in Java.
