Scratch files in Android Studio not working

[RhinoCan]

I often got a real benefit from scrapbook pages in Eclipse so I did a bit of digging and found that scratch files are the equivalent in Android Studio. I found a short video that told me how to create them - see

- and tried creating a very simple one. Within a file named scratch.java, I created this code:

public class scratch {

    public static void main(String[] args) {

        System.out.println("Hello World");
    }
}

There are no errors of any kind indicated in the source code. Whenever I try to run it though, I get:

Error: Could not find or load main class scratch

Process finished with exit code 1

Any idea what I'm doing wrong? I'm guessing that I have to turn something on in Android Studio or install a plugin of some kind but I can't find any instructions telling you to do certain tasks before writing your first scratch file.

I upgraded to Android Studio 3.1.4 the other day. I'm running in Windows 10.

Looks like you forgot the import statement

import java.util.*;

Oops. That was a mistake in copying the code into the question; the import is actually there. If it were missing, I'd get a different error.
