Java Applets cannot be run in Chrome due to outdated technology.
The Java applet uses NPAPI, which is a platform-independent plugin architecture. In July 2015, Chrome version 45 replaced Chrome version 40, which has been supported for over a decade.
You haven’t been able to run Java Applets since then because the Java Plugin no longer works.
There are however extensions such as CheerpJ Applet Runner and IE tab that are capable of running Java Applets in Chrome. How to Run Applets in Chrome?
Running Applets with CheerpJ
A mission-critical Java application or applet can be modernised and preserved with CheerpJ, an enterprise-grade solution. By using HTML5 Pages (including those powered by frameworks such as React and Angular), an organization can either maintain accessibility for existing Java Applets and Applications or modernize them for HTML5 integration.
Java Applets can be run without installing or running Java with CheerpJ Applet Runner for Chrome and Edge. By using Chrome or any other modern browser, you can access Java Applets on modern IT architectures for use with internal or third-party Java Applets.
Microsoft-based enterprise architectures can use CheerpJ Applet Runner via Global Policy Objects on Edge or Chrome to run CheerpJ applets.
Chrome Extension for CheerpJ Applet Runner
For non-commercial purposes, you can use CheerpJ Applet Runner for free. Click on the extension’s icon in your browser’s upper right corner to enable it, then visit your Applet-based site and install the extension. How to Run Applets in Chrome?

With the IE Tab Extension, you can use Java, Silverlight, ActiveX, SharePoint, and other technologies from IE within Chrome.

Due to the lack of NPAPI support in Chrome, IE Tab requires a separate helper executable from you to access local resources.
If you want to use it for non-personal purposes, a license is required.
