Kotlin

Kotlin-1

Kotlin is an elegant general-purpose language with a rich syntax that enables us to write concise and expressive code. Much of its appeal also stems from the fact that it is fully interoperable with Java and has multi-platform support. Kotlin is also an official Android language ranked by Google as the most preferred language for Android app development.

In this course, you’ll learn about type inference in Kotlin as well as about Kotlin’s support for higher-order functions. You’ll cover classes, objects, and other interesting themes relevant to these topics. You’ll finish with operator overloading, extension functions, and scoping functions.

This course is specially designed for Java professionals who want to get into Kotlin development with minimal time and effort. This is not an encyclopedic work on Kotlin. Rather, it focuses on the necessary foundations and the best features that Kotlin has to offer. After completing this course, you’ll feel more comfortable reading and writing Kotlin code.

## Default arguments

Kotlin allows us to provide function parameters with a default value, which is used if the corresponding argument is omitted on the call.

```kotlin
fun String.splitString(separator: Char = ',')
```
When splitting a string with the extension function above (more on extension functions later), we can choose any separator. However, thanks to the default value “`,`” we can also omit it, if the “`,`” is actually what we need:
