BLE communication in Java

This is my first question post.We ask for your help.

I would like to communicate BLE with iOS device using Java language.
Assume Java (peripheral) iOS (central).

I'm looking into a lot of things, but I've found information about peripheral side and advertisement in Java language
I'm having a hard time because I hardly have any.

How can I use Java to communicate and advertise BLE?

What you want to do
·BLE communication using Java language
·Java side (peripheral) iOS side (central)
·Advise in java language

Thank you for your cooperation.
