In Windows 10 there is a notification that opens in the bottom right of the screen and I find them quite useful.
Is there is any way to create Windows notifications in Java? This is what they look like:

I can successfully produce this result using this very simple sample code:
import java.awt.*;
import java.awt.TrayIcon.MessageType;
public class TrayIconDemo {
public static void main(String[] args) throws AWTException {
if (SystemTray.isSupported()) {
TrayIconDemo td = new TrayIconDemo();
td.displayTray();
} else {
System.err.println("System tray not supported!");
}
}
public void displayTray() throws AWTException {
//Obtain only one instance of the SystemTray object
SystemTray tray = SystemTray.getSystemTray();
//If the icon is a file
Image image = Toolkit.getDefaultToolkit().createImage("icon.png");
//Alternative (if the icon is on the classpath):
//Image image = Toolkit.getDefaultToolkit().createImage(getClass().getResource("icon.png"));
TrayIcon trayIcon = new TrayIcon(image, "Tray Demo");
//Let the system resize the image if needed
trayIcon.setImageAutoSize(true);
//Set tooltip text for the tray icon
trayIcon.setToolTip("System tray icon demo");
tray.add(trayIcon);
trayIcon.displayMessage("Hello, World", "notification demo", MessageType.INFO);
}
}

One question how would i set the exclamation mark to it's own texture, i have seen other notifications with custom png files as there icons.

It does not look like that's possible - that seems to be a feature not available in AWT, it's possibly only available in the native windows gui toolkits.

Currently the notification is removed from the action center after it expires. Is there a way to keep it there?

Super answer. Is there a way to stop the system tray icon from preventing JVM from exiting?
MrPowerGamerBR
@JohannesBrodwall if you remove the
trayIcon from the tray (tray.remove(trayIcon)) the JVM will exit. Keep in mind that if you remove it while the notification is still open, the notification will magically disappear.This can be achieved with the SystemTray and TrayIcon classes. Also, if this is a new API for you, you might want to check the dedicated tutorial "How to Use the System Tray".

you can use Notifications with javafx easily with Notification class java.lang.Object org.controlsfx.control.Notifications
public static showNotification(String title,String text){
Notifications notificationTest=Notifications.create();
notificationTest.position(Pos.BASELINE_RIGHT);
notificationTest.title(title);
notificationTest.text(text);
notificationTest.show();//for error noti notificationTest.showError();
}
