This paper provides a recommendation for development teams to adopt Kotlin and explains why some of these Kotlin features will improve Intuit’s current Java development, reducing overhead cognitive burden, which will allow developers to focus on creating value for customers.Ĭommon pitfalls in Java include null references, boilerplate code, and mutability due to the way that the language has been developed. It is interoperable with Java and Google has named it one of the official languages of Android. Kotlin is a statically typed programming language that can run on the Java Virtual Machine. At Intuit specifically, most teams work in Java. Java is an established, well-understood language that has been in existence for over two decades. Most engineers developing server-side capabilities or Android applications use Java.

The current version is a slight variation of the paper featuring me and Katie Levy’s opinions and observations and why we think Kotlin has helped increase our developer productivity velocity. That’s all for Kotlin print functions and quick introduction of Kotlin REPL.The original purpose of this paper was to help drive the consideration to introduce Kotlin at Intuit. Once it is done, start the REPL by entering kotlinc in your terminal/cmd Following is my first code in the REPL. Typically, on a mac, we can use HomeBrew on our terminal to install the kotlin compiler. We can install command line compiler on Mac/Windows/Ubuntu as demonstrated here. W e can do so in our terminal/command line by initiating the kotlin compiler. REPL also known as Read-Eval-Print-Loop is used to run a part of code in an interactive shell directly. InputMismatchException is thrown when the input is of a different type from the one asked. Println('First value should be a float, second should be a boolean. The following code shows print statements in action: fun main(args: Array) ') The println statement appends a newline at the end of the output. The print statement prints everything inside it onto the screen. To output something on the screen the following two methods are used:

Furthermore, we’ll look into Kotlin REPL. Today we will learn how to use Kotlin print functions and how to get and parse user input from console.
