Thank you to those of you who have responded with encouragement, that
has helped a lot.
Just to close out this query, I took the plunge and installed JDK21
(after first uninstalling JDK8) and opened up my project. No errors
reported but the appearance and layout of my various screens was
wrecked. After a bit of Googling I found that the way to set look & feel
had changed from that which I have previously used. After copying and
pasting the revised code into my project - nearly 30 source files - all
is well.
One small niggle remains: when I start NB20, it complains it cannot find
JDK8 and can it use the default. I click 'yes' and all is well. I have
found how to point NB to JDK21 at project level but I cannot find a way
to switch this at global level. Is there an environment variable I need
to know about here?

cool! This is probably one of the best ways how to get into
programming. Find something you want to write and then try to get
there somehow with the help of books/guides etc.
... I didn't realise that the professional development community had
moved on and was now plugged into Oracle and Java.net which seem to
be under totally different care and maintenance.
NetBeans has also a JDK downloader integrated, if you want to see all
the different versions and vendors you can access it under:
Tools -> Java Platforms -> Add Platform -> Download OpenJDK
So it seems that I need to refocus my attention to JDK21 from Oracle
and cross my fingers and hope that my current project survives the
sudden upgrade.
If you encounter problems, upgrade in steps, 8->11->17->21. But most
programs will work fine on 21 if you don't have too many trouble
making dependencies.

Some of this confusion is caused by the fact that there is no longer
a separate JRE download. Java.com was targeted at end users, not
developers. There is indeed no update to the Java 8 JRE as the JRE
is discontinued. The JDK is a different story.

Why is everyone avoiding answering Judi’s question?
On the NetBeans main page, it says indirectly that you can't
install with java 8, you need 11+
Deployment Platforms
The Apache NetBeans 20 binary releases require JDK 11+, and
officially support running on JDK 11, 17 and 21.
https://netbeans.apache.org/front/main/download/nb20/
I don’t pretend to be the expert but the answer to Judi’s
question is: download newer (post-v8) versions of Java from
Zulu (https://www.azul.com/downloads/?package=jdk#zulu) or some
other OpenJDK site.
Cheers,

java isn't going to update to the next major version on
windows. I don't think the newer JDKs have even an updater
anymore (not sure, might be vendor dependent).
The easiest way to get started on windows is to use one of the
community installers which bundle a current JDK with NB in one
package. If you don't want that, then check the requirements
on the download page and install a supported JDK of a vendor
you prefer.
