Then write your code and run it with the appropriate module selected in the Use classpath of module list.īoth scratches and worksheets use the compiled versions of connected modules.

Scratches are not tied to projects you can access and run all your scratches from any IntelliJ IDEA window on your OS. Scratch files (or just scratches) let you create code drafts in the same IDE window as your project and run them on the fly. IntelliJ IDEA and Android Studio support Kotlin scratch files and worksheets. Check out these three handy ways to run Kotlin code instantly in different environments: However, if you want to quickly see how a function works or find an expression's value, there's no need to create a new project and build it.
