Hi! I need help! How come I am getting this message? Error: Could not find or load main class Instructions

I can't seem to make the compiling work, even though I erased everything and started over. The message still doesn't want to go away... help!

Davy;

Welcome to Treehouse! Sorry you are experiencing issues.

Can you provide a little bit more information please? Are you working in workspaces, doing a challenge, or something else?

Thanks,

Ken

Hello! Yes I am doing the exercises in workspaces. It was in the beginning when I would make a mistake in the coding, that message would show. But even after I erased the whole thing and started over the message was still there. So I had to create a new workspaces and start over. Maybe just a bug?

solutions 1- don't forget write a class name by capital (public class -Introductions- ) first character after class is capital java it's case sensitive . 2- if you want to run an app you must write a main method after the class : ( public static void main ( String [] args) ) , without main method java compiler will not run the app . 3- then inside a main method { write what you want of code } i hope i helped you to fix your problem
