I am trying to get the view count of a youtube video in Jsoup. I started by getting the title which worked well but am having trouble getting the view count which is in a span class.
Here is my code so far:
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import java.io.IOException;
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JButton;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
public class HigherOrLowerYoutube {
public static void main(String[] args) {
try {
Document doc =
Jsoup.connect("https://www.youtube.com/watchv=omlFsLz2WKM").get();
println(doc.title());
} catch (IOException e) {
e.printStackTrace();
}
}
private static void println(String string) {
System.out.println(string);
}
}
Try:
System.out.println(doc.select(".watch-view-count").first().text());

I'm trying to create an image file of a graph with vertices,edges and weigths with JgraphX and mxGraph.
I'm new to this thing of JGraph and stuff and found a tutorial to do this.
But I can't understand why when it creates the image, it shows the vertices and edges good but the weights are "Null".
I'll post the code below together with a image.
import com.mxgraph.layout.mxCircleLayout;
import com.mxgraph.layout.mxIGraphLayout;
import com.mxgraph.util.mxCellRenderer;
import org.jgrapht.ext.JGraphXAdapter;
import org.jgrapht.graph.DefaultDirectedGraph;
import org.jgrapht.graph.DefaultDirectedWeightedGraph;
import org.jgrapht.graph.DefaultEdge;
import org.jgrapht.*;
import org.jgrapht.graph.DefaultUndirectedWeightedGraph;
import org.jgrapht.traverse.BreadthFirstIterator;
import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
public class JgraphTest{
DefaultDirectedWeightedGraph<String, DefaultEdge> g = new DefaultDirectedWeightedGraph<>(DefaultEdge.class);
BreadthFirstIterator bfs;
public void crearGrafo(){
g.addVertex("Ninja1");
g.addVertex("Ninja2");
g.addVertex("Ninja3");
g.addVertex("Ninja5");
g.addVertex("Ninja8");
g.addEdge("Ninja1","Ninja2");
g.addEdge("Ninja2","Ninja1");
g.addEdge("Ninja8","Ninja3");
g.addEdge("Ninja3","Ninja5");
g.setEdgeWeight("Ninja1","Ninja2",12);
g.setEdgeWeight("Ninja2","Ninja1",2);
g.setEdgeWeight("Ninja8","Ninja3",10);
}
public void mostrarGrafo() throws IOException {
JGraphXAdapter<String, DefaultEdge> graphXAdapter = new JGraphXAdapter<>(g);
mxIGraphLayout layout = new mxCircleLayout(graphXAdapter);
layout.execute(graphXAdapter.getDefaultParent());
BufferedImage image = mxCellRenderer.createBufferedImage(graphXAdapter, null, 2, Color.white, true, null);
File imgFile = new File("src/graph.jpg");
ImageIO.write(image, "JPG",imgFile );
}
}
Image created after executing the algorithm
Thank you everyone and I hope I didn't miss any information, please let me know if I forgot to post something.

I am using Java Fx and Scene builder, and my code runs without exceptions, but the combobox remains empty, and I can't understand why. I set identity ID and OnAction field but still it doesn't works. Here is my controller:

I am using this code to see whether the PNG images can be properly loaded to create JLabels, Icons, etc but I get the error that:
java.lang.IllegalArgumentException: input == null!
at javax.imageio.ImageIO.read(Unknown Source)
at common.ResourcesToAccess.<init>(ResourcesToAccess.java:21)
at common.ResourcesToAccess.main(ResourcesToAccess.java:29)
Why do I see that error message?
try with
this.getClass().getClassLoader().getResourceAsStream("images/blackCursor.png")
it is looking in your classpath so no more src directory there
