How can I convert a part of Java source file to Kotlin?

Question

In my Kotlin project, I have some parts of Java code that I want to convert to Kotlin. The menu item that converts the Java file to Kotlin is disabled because it's not a whole file I want to convert.

How can I convert Java code to Kotlin?

Answer 1

With Android Studio 3.0

You don't need to install any plugin to convert java code to kotlin code. Now, Google is officially supporting Kotlin language.

• Android Studio Menu -> Code -> Convert Java File to Kotlin File

Before Android Studio 3.0

If you are using older Android Studio ( which is below version 3.0 ) there is a Kotlin tool under the menu.

Installing Kotlin plugin :

• Android Studio Menu -> File -> Settings -> Plugins -> Browse repositories -> Kotlin

Converting Java Code to Kotlin Code :

• Select your java class file from project structure.
• Android Studio Menu -> Code -> Convert Java File to Kotlin File
