Question

I’m just learning java and following a book.

I have a program written via text editor and run commands via cmd.

I’ve complied 1 program thru javac and executed thru java no problem. (Hello)
Then I modified that to add a comment to the class, named file Hello2.java. I compiled it with no problems, but upon execution, I receive this error: Could not find or load main class Hello2.

I have classpath and path set correct;y on environment variables.

Ideas?

UPDATE

Hello.java

  public class Hello {
      public static void main(String[] args) {
          System.out.println("Hello, world!");
      }
  }

Hello2.java

//Filename Hello2.java
//Written by 
//Written on 

public class Hello2 {
    public static void main(String[] args) {
         System.out.println("Hello, world!");
    }
}

/*This class demonstrates the use of the println() method to print the message Hello, world! */

Answer 1

I’ve found the solution to my problem. I know it’s not a code problem. But what I did is that I deleted CLASSPATH from system variables and everything now works…at least for now.

Thanks a lot everyone for your inputs, much appreciated!
