Shortest Path from source to Vertex :- Dijkstra Algorithm

Shortest Path from source to Vertex :- Dijkstra Algorithm:- Dijkstra  Algorithms is an algorithm use to find the shortest path from source vertex to a given vertex. package Graph ; import java.util.HashMap ; abstract public class DirectedGraph { Vertex [] vertexlist = new Vertex [ 10 ]; HashMap < Character , HashMap < Character , Integer >> edgelist = new HashMap <>(); Vertex vertex ; //count of vertex and edge static int vertexcount = 0 ; int edgecount = 0 ; /* * This function takes a label and insert in the vertex list as well as edge list since it is new vertex it will add * null to its adjoining vertices */ int addVertex ( char label ) { vertex = new Vertex ( label ); vertexlist [ vertexcount ]= vertex ; System . out . println ( vertexlist [ vertexcount ]. label ); edgelist . put ( vertex . label , null ); vertexcount ++; return vertexcount ; } int addEdge ( char label , char []

How to build a project in eclipse with MAVEN build tool?

How to build a project in eclipse with MAVEN build tool? Step 1:- Install maven and set the path in my computer. Once path is set for java and maven you will get a screen With version installed in your system. Step 2:- Write a command mvn archetype:generate to build a project of your choice.This will give you a option to select a project from list. Step 3:- As soon as this operation will complete maven give you choice to choose project.Search for maven-archetype-webapp this will build a web project with basic structure. Step4:- Follow the below procedure to give name , version ,package ,artifact and group id of your choice. Step 5:- You will get screen with build success.Congrats your project is build in directory. Step 6: Go in the directory to check for the folders automatically created by maven. You will get pom file and src folder and the package folder. Step:-7  Move to the directry having pom.xml and run mvn ecl
