I know that Java is no longer supported in MacOS, but need some guidance with which website to use to download JAVA or something similar.

You understand incorrectly. Java is no longer supported and issued by Apple. But Java is not gone. Java is readily available for free download for individual use from its owner, at Java.com. (Do not use any other web site for download, unless you LIKE having malware.)

Apple-Silicon M1:

Apple says every well-behaved ordinary Aplication (that does not use Virtualization) will run on Apple-Silicon. It will use Rosetta emulation to translate the Intel binary to M1-binary.

Your Apps will run and not crash while being executed on a a completely different processor than the one the developer used. You are a lucky fellow indeed.

If you are using graphics intensive apps, the workflow that the developer intended and optimized has been changed. Different parts may be assigned to graphics processors and main processors, and certain parts that used Native Intel instructions for speed may now be emulated in a subroutine.

But it runs, and you can get your work done, which is what Apple promised and delivered.
