Write a Java program (based on a graph traversal algorithm you've learned in this class) that, for a given undirected graph, outputs: the vertices of each connected component. Your programs should take inputs from a file via the command line with the following structure in the input file. Each line of the input file represents a graph. The first number in a line specifies the number of vertices in the graph. Then pairs of vertices define the edges. An example of an input file is as follows: 5 (1,2) (3,4) (3,5) (4,5) 4 (1,2) (2,3) (1,4) It specifies two graphs. The first graph has five vertices (1,2,3,4,5) and four edges. The second graph has four vertices (1,2,3,4) and three edges. Proper output should look (something) like: Graphl: Two connected components: {12} {3 4 5} Graph2: One connected component: [1 2 3 4] You must test your programs on a nontrivial input file (with at least 3 graphs and each graph having 7-10 nodes). Your output should be formatted nicely so that it is easy to read.
