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 put some music or a short clip of a sound to my project. I try some helps from here. It kinda work, but I could not hear anything. It just wrote that its playing.
I found a lot of examples, but nothing is working for me. Maybe you can help me with that AudioStream, AudioPlayer. Many people are using it. How can I use it in my Java Eclipse 4.4.0?

songik.start();
System.out.println("Song is playing...");
System.out.println(songik.getFormat());

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:

String query = "SELECT * FROM maginfo";
PreparedStatement dindb = Conexiune.conexiuneBd.prepareStatement(query);
ResultSet rezultate = dindb.executeQuery();
while (rezultate.next()) {
String Nume = rezultate.getString("nume");
ObservableList<String> list = FXCollections.observableArrayList(Nume);
meniu.getItems().addAll(list);

I've recently started playing around with JavaFX :) I'm working on a little pet project and one of the issues I'm currently having is animating the resize of a VBox when a child is added or removed to/from the VBox.
I've got "the kids" fading out and then being removed from the VBox already. Once that animation completes I need the VBox height to resize preferably as an animation and not like the instant change it currently does.
The other threads that I've found are similar but I think they aren't quite exactly what I'm looking for.

And thanks in advance for help or suggestions.
Probably not very helpful any more. I am currently working on the same thing.
You just need：
1. Add the same animation(if they all supposed to be same) to each of the remaining children in the VBox.
2. Use ParallelAnimation to make them run at the same time.
3. Use again a SequentialAnimation for you "kids" fading out animation and the parallel animation. This ensures they will not happen concurrently since multiple threads could run simultaneously.
4. To reach still the same view as what the instant update does, use animation/timeline.setonFinished(EventHandler()) to updates the screen
I want to snap a picture of a webpage using the JavaFX "snapshot" method. My problem is that the WebView doesn't load the webpage before I snap the snapshot. Putting the call to snapshot inside a listener that tests when the webview's getLoadWorker succeeds doesn't work. I get inside the "if" of the listener (see below) before the page actually loads.
To demonstrate this, the following standalone code both attempts to snap the snapshot upon "success" and allows you to click a button to do the same. The button click (marked "BUTTON") works, because you click it after the webpage loads. However the automatic snapshot (marked "AUTOMATIC") produces a blank image, because for some reason the worker state is reaching "SUCCEEDED" before the page is actually loaded.
Can someone tell me what I'm doing wrong with the getLoadWorker listener? Thank you for any help!
