Let’s start by saying there are only two browsers that still officially support Java. Just Internet Explorer and Safari. Now, there are workarounds for certain browsers, while Firefox is being the only exception out of all major browsers.

Java applets are used to provide interactive features to web applications

  • Java applets are small applications written in the Java programming language.

  • They can be installed and run automatically as part of a web document.

  • Any browser that has JVM operating in it can run Java applets.

  • To operate it in a browser, you must create an HTML text file with a tag that loads the applet.

  • Easy migration: use the Opera assistant to transfer exiting data, such as bookmarks, passwords, etc.

  • Optimize resource usage: your RAM memory is used more efficiently than in other browsers

  • Enhanced privacy: free and unlimited VPN integrated

  • No ads: built-in Ad Blocker speeds up loading of pages and protects against data-mining

  • Gaming friendly: Opera GX is the first and best browser for gaming

  • Download Opera

If you get the error your browser is not set up to run the applet program in Java, you’ll need to enable Java in browsers from the Java Control Panel and do some tweaking.

Depending on your browser of choice, of course, we have instructions on how to run java applets. Check the steps below.

How can I run Java Applets in a browser?

1. Enable Java content for browsers

Before you can run the applet program in Java on your favorite browser, you need to enable Java content. This can be done via Settings, after you install Java on your PC.

The Java applet will then be displayed on the web page by making use of the deprecated applet HTML element, or the recommended object element.

  1. Download and install Java for Windows.

  2. In the Windows Search bar, type Java and open Configure Java from the list of results.

  3. In the Java Control Panel, check the Enable Java content for browser and Web Start applications box.

  4. Click on Apply and OK to save the changes.
