How do I run Java applets? [duplicate]

Why is the Java plugin (JRE) disabled in Chrome?

Is there a way to run a Java applet on Chrome or Firefox? I get the error message on the Java test page that Java won't run on Chrome or Firefox anymore because of the non-supported NPAPI.
I have an old set of *.class
files with an .html
to run it, and I just want to be able to run this applet somehow. But how?

Is there a way to run a Java applet on Chrome or Firefox?
No. Applets are no longer supported in Firefox or Chrome.
Firefox no longer provides NPAPI support (technology required for Java applets)
As of September, 2018, Firefox no longer offers a version which
supports NPAPI, the technology required to run Java applets. The Java
Plugin for web browsers relies on the cross-platform plugin
architecture NPAPI, which had been supported by all major web browsers
for over a decade. The 64 bit version of Firefox has never supported
NPAPI, and Firefox version 52ESR is the last release to support the
technology. It is below the security baseline, and no longer
supported.
Source Java and Firefox Browser
Chrome no longer supports NPAPI (technology required for Java applets)
The Java Plugin for web browsers relies on the cross-platform plugin architecture NPAPI, which had been supported by all major web browsers for over a decade. Google's Chrome version 45 and above have dropped support for NPAPI, and therefore Java Plugin do not work on these browsers anymore.
Source Java and Google Chrome Browser
So how do I run Java applets?
Use the AppletViewer, from a JDK before Java SE 11.
The appletviewer command allows you to run applets outside of a web
browser.
SYNOPSIS
appletviewer [ options ] urls ...
DESCRIPTION
The appletviewer command connects to the documents or resources
designated by urls and displays each applet referenced by the
documents in its own window. Note: if the documents referred to by
urls do not reference any applets with the OBJECT, EMBED, or APPLET
tag, then appletviewer does nothing. For details on the HTML tags that
appletviewer supports, see AppletViewer Tags.
Note: The appletviewer is intended for development purposes only.
Source appletviewer - The Java Applet Viewer
Alternatively read the Oracle White Paper (pdf) Migrating from Java Applets to plugin free Java technologies, which recommends Java Web Start:
Java Web Start has been included in the Oracle JRE since 2001 and is
launched automatically when a Java application using Java Web Start
technology is downloaded for the first time. The conversion of an
applet to a Java Web Start application provides the ability to launch
and update the resulting application without relying on a web browser
See What is Java Web Start and how is it launched? for more information.
Note that both Java Applets and Java Web Start were removed completely in
Java SE 11 (release September 2018). From that version on there is no (supported) way to run Applets or Web Start applications.

Note even webstart is dropped in java 11 and the 'official' way is now to use j9+ modules to create 'lean' downloadable apps although j8 remains supported for 'deployment' = webstart for a few more years

@jerrrrro: apparently you missed the last decade and a half, when Java sandbox (= applet/webstart) bugs were one of the biggest and most frequent vectors for system infections and breaches. Every few weeks all the security websites announced "huge danger from browser java! remove java from all your systems NOW!", a few weeks later "okay, Sun/Oracle patched that one", a few weeks later "ANOTHER huge danger from java!". The browser makers got tired of this and removed support permanently, so Oracle made the best of it: "we didn't really want to run in browsers anymore"

@jerrrrro, also, Java applets (and Flash applets) were obsoleted by HTML5 and various WebApis, which allows actual integration into the page as a whole rather than just an embedded box with basically no legal interaction with the rest of the content.

If you already have the files on your machine, you can try the appletviewer that (used to? still does?) ships with the JDK (Java Development Kit).
