HelloWorld.java

package DiscordBunkerOnlineBot;

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("dasdasdasdasdasdasd");
    }
}

I have problem with Error:

Could not find or load main class HelloWorld Caused by: java.lang.ClassNotFoundException: HelloWorld

I don't know how decide it.

I wrote:

jar cfe HelloWorld.jar HelloWorld HelloWorld.class

To create a .jar file

I tried writing:

jar cfe HelloWorld.jar mypackage.HelloWorld HelloWorld.class

It didn't help.

I tried to create a new project, it worked, but I want that to work on my main project.

  • Your class is in a package. Your jar layout needs to reflect that. – tgdavies Aug 03 '23 at 23:16

    *And i wrote "jar cfe HelloWorld.jar HelloWorld HelloWorld.class" that create .jar file* Where did you do that - in the terminal? If so, what was the prompt, and what did you do *before* that? Hint: learn to copy and paste from a terminal when you post code here – g00se Aug 03 '23 at 23:34
  • How did you try to *run* the Java application. 'Cos the error message is saying that you (somehow) told it to run `HelloWorld` but the actual class name is `DiscordBunkerOnlineBot.HelloWorld` in the source code is. It seems to me that you have made a number of mistakes ... and you haven't given us anywhere like a complete description of what you actually did. – Stephen C Aug 04 '23 at 08:42
