Answer 1

If you're using Android Studio, you can just:

• Configure Kotlin in project
• Right-click on .java file and select 'Convert Java File to Kotlin File'

If you copy paste the Java snippet into.kt file, it will also ask you if you want to convert it automatically.

Your above java code should be like the following.

var service = RetrofitClientInstance.getRetrofitInstance().create(GetDataService::class.java)
