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.

# Introduction
With the help of **extension functions**, classes can be extended, even if they are `final`,  like `String`.

Extension functions allow us to declare functions outside a class, and yet their call looks like that of a method of that given class.

## Example

Suppose that, in a project, it is necessary to calculate the `square` of an integer.

A suitable function for this is a quick write, as shown here:
