Question

Social Graph project is  network which  consists of  two things :
  People   is  represented  in the  Graph by Nodes  or  Vertices (the vertex should  consist of  name of  the person)
 Relationships  is  represented in the  Graph by  edges or arcs
The  project should have at least  two class with following methods :
 addNode add vertices to graphs(New person in the  Graph Net )
removeNode removes vertices to graphs(remove person from the graph Net)
addEdge adds connections or paths between vertices in graphs(make  new relationship between two persons in the  graph )
removeEdge removes connection or paths between vertices in graphs (remove the relationship between two persons in the  graph )
contains check if a graph contains a certain value
hasEdge checks if a connection or path exists between any two vertices in a graph

IN JAVA LANGUAGE PLEASE and thnak you !
