Java Applets cannot be run in Chrome due to outdated technology.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.

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