How can I run a .jar file in the app?

I want to try to read a .jar file inside the app, but how do I do it?
execute it if it is loaded as an asset and it is displayed and the user can communicate with the file.jar

using jar you can create extension and then use it according to you need.
btw which jar you want to use?

Thank you for your interest and support …Converting it to an extension does not help me because it is like an already executed program … It is as if I wanted to execute a .jar file within the app

Simple answer: You can’t.
