Creating Push Notifications With Java

  Reading Time:

In this tutorial, I will be showing you how to create push notifications using java. I will show you how to create one using SystemTray in AWT. JavaFX has not implemented their version as of now. While there are ways around it, I find that it becomes to tedious to implment compared to AWT, so I will not cover any methods.


Using AWT

Showing a notification is pretty easy using AWT. We need to utilize the SystemTray to create a notification. It must be noted, not all OS's use SystemTray, so you should do a quick check, in your app, prior to pushing. Since AWT is included in the JDK, we do not need any special dependencies.

package com.triippztech;

import java.awt.*;

public class Main  {

    public static void main(String[] args) {
        try {
        } catch (AWTException e) {

    public static void pushNotification() throws AWTException {
        // Do a check to ensure SystemTray is supporteed for this OS
        if (SystemTray.isSupported())
            //Obtain only one instance of the SystemTray object
            SystemTray tray = SystemTray.getSystemTray();

            //If the icon is a file
            Image image = Toolkit.getDefaultToolkit()

            //Alternative (if the icon is on the classpath):
            // Image image = Toolkit.getDefaultToolkit().createImage(

            TrayIcon trayIcon = 
                new TrayIcon( image,"Java AWT Push   Notification");

            //Let the system resize the image if needed

            //Set tooltip text for the tray icon
            trayIcon.setToolTip("Notification Demo");


            // Create our message and what type of Notification this is.
                "Wake up!", 
                "Java Push Notification Demo", 
            // If you want to add a timer for it to go away
            // trayIcon.wait(10000);
        } else {
            //Handle your errors accordingly
            System.err.println("SystemTray is not supported on this OS");




Go ahead and play with these Notifications. Try customizing them more, and utilize them in your application!
