Running Java Applications

You must have a Java development kit (JDK) installed, preferably the latest version (JDK 21 or later).
You can download it from here  .

To download the Java Application, click the link on the web page of the relevant simulation. The format of the application is an executable Java Archive (JAR) file which you can download to any folder on your computer (e.g. the default download folder) . You can then start the application by double-clicking the JAR-file in the file explorer.

 

How safe is it to run the applications?

You may be, and should be, sceptical to download and run a runable file from the Internet. But my website is secure (HTTPS) which means that it has a SSL certificate issued by  Bitdefender   and all communication with the website is encrypted. And if you look at the top of this page you will see that my domain "paulba.no" is secured by  SiteLock , the global leader in website security,  which means that my website is scanned every day, and if the shield says "passed" it is guaranteed free of malware. (Click on the shield to see the guarantee.)  But the best security lies in the fact that both the SSL certificate and SiteLock guarantee that the 'Company'  Paul B. Andersen is genuine. And what's more, to get a ".no" domain you must apply to Norid   . The result of a whois lookup in Norid can be found here .

I would have to be pretty stupid if I had  malicious programs on my website which can be tracked back to me.

So I will answer the question above like this:

It's very safe.
