my project is this :

what should I do to find the button to run my scala program

there is no run button

Answer 1

As I cannot comment, I will write here: you must point the scala class and right click on it, and then you have the Run. In the pictures you are trying to run the java class

Answer 2

Few things: a) Check to make sure, your source directory is included as module ie File > Project Structure. In the attachment below you see my modules

b) Check to make sure you have included your scala library, I believe you have this setup.

c) Last resort, see if you can add your object as Application ie Run > Edit Configuration & the following

Hope this helps, enjoy!

Answer 3

You need a scala plugin to run a scala file. And find more at the get started documentation of idea.
