This course aims to share with you the power and the beauty of Kotlin. Kotlin code might be compiled not only to JVM bytecode but to JavaScript and Native code as well, but this course is focused on Kotlin/JVM. It’s a pragmatic language with a very low learning curve, and can be quickly grasped by Java developers.

Kotlin is 100% compatible with all existing Java frameworks, and has good tooling support. It can be used almost everywhere Java is used today: for server-side development, Android apps, and much more. Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. When this option is enabled, you can write and execute code line by line, and only the new code will be executed with each new run.The Kotlin programming language is a modern language that gives you more power for your everyday tasks. Use REPL: executes the script incrementally. Interactive mode: runs the code each time you stop typing. Use classpath of module (only applicable for scratches): specifies the module with your custom classes if you want to use them in a scratch. The following options are available for running Kotlin scratches and worksheets: In the top-left corner of the editor, click or press Ctrl+Alt+W. Give the worksheet a name and press Enter.

In the Project tool window, right-click the directory in which you want to create a worksheet and select New | Kotlin worksheet. This lets you use project-specific classes without any configuration, but ties a worksheet to a project.įrom the main menu, select File | New | Scratch File or press Ctrl+Alt+Shift+Insert, then select Kotlin. They can be accessed from any project, but you have to specify where to look for the classes in case you are using project-specific classes. The difference between scratches and worksheets is that: This is useful for testing and prototyping purposes. Scratches and worksheets allow you to create a temporary file and execute it straight away. Users/me.user/Users/me.user/IdeaProjects Res3: ! = /Users/me.userįiles.walk(res3, 1).forEach
