![]() ![]() Run the playground again and you’ll see the following output: Choose or type joinToString() to get the desired output: It’s better to show the names separated by commas, right? Do so by adding a dot to the right of the args parameter, and you’ll see the following: Run the program, and you’ll see the following output: Now, change main to receive those arguments: One way to test your Kotlin code is by passing in arguments into your playground. You’ll start by passing arguments into your app. Target Platform: Select JVM, JS, CANVAS or JUNIT as targets for the code you write.Program arguments: Set input arguments for your main function.Kotlin Version: Choose the version to build your program.In this section, you’ll a look at each configuration and how it affects the playground. Playgrounds allow you to configure parts of the environment. Note there’s already a Hello World program written for you.Ĭlick Run, located on the right, to build and run the code.īecause this is a console app, it will print Hello, world!!! in console output. ![]() To open the playground, go to, where you’ll see the following: If you’re unfamiliar with the language, review our Kotlin for Android tutorial first. The classes and methods of Android SDK often handle a reference on a "Context" object.Note: This tutorial assumes you have experience developing in Kotlin.For more details, see Generating an Android application. If the Kotlin code entered requires specific permissions, they must be explicitly defined when generating the application.Kotlin is case-sensitive: make sure you always use the same lowercase and uppercase characters in the function names.It is recommended to import these elements before declaring the method. Caution: you need to import the classes used in the native Kotlin code with the "Import" keyword.The return values of methods must be of a primitive type (integer, real, string, etc.).The parameters of procedures written in Kotlin must be of a primitive type (integer, real, string, etc.).Ĭaution: The float type is not supported, it can be replaced with the double type.In Kotlin procedures, parameters are automatically passed by value. ![]()
