Learn Kotlin code structure focusing on file and class organization, package usage, naming conventions, and unique language features such as package-level functions, optional main arguments, and no need for static modifiers or semicolons. Understand how these elements combine for concise and readable Kotlin code.
Unlike Java, there’s no strong relationship between the file name and class name in Kotlin. We can put as many public classes in our file as we want, as long as the classes are related to one another and the file doesn’t grow too long to read.
Naming conventions
As a convention, if our file contains a single class, we name our file the same as our class.
