I have the below code,

import javax.swing.*;
public class MyFrame
    {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Test Frame");
        frame.setSize(400, 300);
        frame.setVisible(true);
        frame.setDefaultCloseOperation
        (
            JFrame.EXIT_ON_CLOSE
        );
    }
}

However when I 'Run' in Eclipse, it throws me an error that the selection could not be run. Im new to java, so Im not sure what's happening.

I tried to change the main class in Run Configurations, and I set it to MyFrame, however it's telling me that it can't find that class.

what is the name of your file? does it `MyFrame.java` – Youcef LAIDANI Jun 23 '18 at 15:58
That exact code works as expected in the IDE I have on-screen.. – Andrew Thompson Jun 23 '18 at 16:07
`Error: Could not find or load main class MyFrame` – Mike K Jun 23 '18 at 16:08
I even went to https://www.onlinegdb.com/ and got the same error. Perhaps a configuration issue – Mike K Jun 23 '18 at 16:09
As @YCF_L asks, what is the name of your file? – Hovercraft Full Of Eels Jun 23 '18 at 16:09
The name of my file is `frame.java` – Mike K Jun 23 '18 at 16:10

@legoMyEgo the name should match the public class's name. – Coder-Man Jun 23 '18 at 16:11
Well there you go. The file name should match the class name. – Hovercraft Full Of Eels Jun 23 '18 at 16:11
Tip: Add @HovercraftFullOfEels (or whoever, the `@` is important) to *notify* the person of a new comment. – Andrew Thompson Jun 23 '18 at 16:11
Thank you, everyone – Mike K Jun 23 '18 at 16:11
