How to display charging stations within reachable range?

Hello! I need to display charging stations within reachable range in Java. I found this document on how to implement it https://developer.tomtom.com/maps-sdk-ios/ev-charging-stations-availability , but it’s written in SWIFT and it seems that classes are different between Java and SWIFT. Could you suggest me what object I should use to implement it or even better, share documentation with Java examples?
