Hello u work now with java and kotlin and want to know that when i run java app where is the code in memory or instruction set in jvm,
My question where is my code in JVM?

Not quite sure that I understand your question

In general, there are no difference between Java and Kotlin after they are compiled all them are just .class files with bytecode which run by JVM. If you want to know how JVM works  and what is process of bytecode execution, there are quite a lot of articles in google about how JVM works under the hood

Thank you for you response,
Yes i know that, after compilation and when the class loader load the class where is the instruction set store in the memory are they in stack or what

Yes, in memory, I believe Metaspace is used to store this runtime cache for classes and jit compiled binaries
