Create a public class GraphAnalysis that provides a single static method named isUndirected. isUndirected accepts an UnweightedGraph from cs1.graphs and hould return true if the graph is undirected and false otherwise. If the passed graph is null, throw an IllegalArgumentException. ach node in the graph has a set of neighbors that you can retrieve representing links rom that node to other nodes. If the graph is undirected, if there is a link from A to B ther here is also a link from B to A. So if B is a neighbor of A, then A should also be a neighbor of B. Note that you do not need to solve this problem recursively, since there is a concise terative solution. or reference, cs1.graphs.UnweightedGraph has the following public properties: 1 public class UnweightedGraph { public Set getNodes (); // returns all node in the graph 3 } 2 And csl.graphs.GraphNode has the following public properties: 1 public class GraphNode { public Object getValue(); // returns the value public Set getNeighbors(); // returns the neighbors of this node 3 4 }
