Question about installing Java on a Windows 11 PC
Often when warning about Java security issues what they’re warning about is Java applets. Those are essentially things where a website gives your web browser a bit of code to run.

Java in general is no more and no less vulnerable than any other programming language / framework. More on reddit.com
