so actually I have worked in both Java and Kotlin. Initially I started working in Java for an e-commerce application. I mean in past I was working in retail domain and recently I joined in automotive domain. So in both I have used Java and Kotlin and I have used almost all the scenarios like thread then coroutine then many things like network calls then UI and Java code interaction then timers. Many technology I have implemented with Java and Kotlin and other things compared to Java and Kotlin. In Java there is no null safety and in Kotlin we can use a null safety. So yeah I have used almost all the things in Java and Kotlin.
