Run single java file with standard main(String [] args) method - Android Studio

Question

To start with - Yes, I know that this is crazy/strange. But I need it :).

I want to find simpliest way to run single java file (and prefer non-terminal answers :) - if they are possible ) in Android Studio. I mean random .java file from my Android project in which I'll write main(..) method. And there's one more thing: I don't want to create any new modules (I've already seen answers about adding Java library module). I just want to click something and run my (single) file, the same way as I can do it in Eclipse. Is it possible?

Answer 1

One thing that might be confusing you, like it was confusing me:

If there is the standard method to start Java application

public static void main (String[] args ) {
// your block here

}

Android Studio will automatically give an option "Run YourClass.mainActivity()", when you right-click anywhere in the editor's editing space.

Just right click in the Java file and there will be an option to run that particular Java class.
