Breadth First Search Implementation in Java For Graph Class Design and DFS implementation please refer to below link:- depth-first-search-implementation-in-java /* 1. Pick a vertex. 2. Get Adjacent Vertex. 3. Insert in queue ( at tail) 4. Remove vertex from queue( head) 5. Do until no vertex left in a queue. */ void searchBFS () { //this is how we define queue using LinkedList Queue < Character > queue = new LinkedList < Character >(); queue . add ( vertexlist [ 0 ]. label ); while (! queue . isEmpty ()) { //element at head (Function in main graph class please use above link) ArrayList adjvertex = getNeighbours ( queue . peek ()); System . out . println ( queue . peek ()); //element removed at head queue . remove (); if ( adjvertex != null ) { for ( int i = 0 ; i < adjvertex . size (); i ++) { //element added at tail queue . add
