Using different languages within the same project is quite common; I came across projects where a mix of Java and Scala files formed the code base. Could we do the same with Kotlin? Absolutely. Let's work on the project created earlier, . You should see the following directory structure in your IntelliJ (the standard template for a Java/Kotlin project):

Project layout

You can place Java code within the folder. Add a new package to the folder with the same name as the one present in the  folder: . Create a New | Java class named and use this code for the purpose of the exercise:
