Question
IN JAVA:
Modify the below code to add Savannah in the graph with edges to Atlanta, New York, and Miami.
Code:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class DisplayUSMap extends Application {
@Override // Override the start method in the Application class
public void start(Stage primaryStage) {
City[] vertices = {new City("Seattle", 75, 50),
new City("San Francisco", 50, 210),
new City("Los Angeles", 75, 275), new City("Denver", 275, 175),
new City("Kansas City", 400, 245),
new City("Chicago", 450, 100), new City("Boston", 700, 80),
new City("New York", 675, 120), new City("Atlanta", 575, 295),
new City("Miami", 600, 400), new City("Dallas", 408, 325),
new City("Houston", 450, 360) };
// Edge array for graph in Figure 28.1
int[][] edges = {
{0, 1}, {0, 3}, {0, 5}, {1, 0}, {1, 2}, {1, 3},
