This would seem very stupid, but is it necessary to attach the java bin address to Path in the environmental variables?

I also already have an environmental variable called Path - and its value is `C:\Users\core\AppData\Local\Microsoft\WindowsApps` - I don't know what this variable does, but I've read this [Stack overflow question](https://stackoverflow.com/questions/4477660/what-is-the-difference-between-user-variables-and-system-variables) and realized that handling these should be done with care. Do I need to change the value of Path to my java bin address `C:\Program Files\Java\jdk-11.0.2` or will this not be necessary if I use an IDE?

Any help would be truly appreciated. Thank you.
