Understanding Kotlin code structure
When you start programming in Kotlin, your first step is typically to create a new file, which usually has the .kt extension.
In contrast to Java, Kotlin doesn’t strictly enforce a one-to-one relationship between the filename and the class name. While you have the flexibility to include multiple public classes within a single Kotlin file, it’s generally considered best practice to group only logically related classes together in one file.

Additionally, packing multiple public classes into a single file can make it harder to search for specific functionality, as the project overview may not display all available classes.
Naming conventions
As a convention, if your file consists of a single class, it is recommended to name your file the same as your class.
When your file contains multiple classes, the filename should describe the...
